Transball is a homebrew MSX game created by Santi Ontañón Villar in 2016.

Player pilots a spaceship with controls simmilar to Asteroids, but with gravity - equipped only with turning, dash and shooting with limited fuel.

The game supports three types of scrolling, selectable on the main menu with 6/7/8, the first one being very blocky and I suggest not using it if you plan on mastering the set.

While tempting, I also don't suggest tuning the game speed using the in-game feature very low - x0.5 speed is laggy.

Set contains level completion achievements, alongside with challenges for first 12. This guide will prioritize the second type.

Precision Extraction (4)
Complete Level 01 in under 8 seconds

Level where you learn how to control your ship - you're tasked with picking up the energy sphere and transport it to the top of the screen - ball and spacecraft try to orbit around themselves, so one needs to precisely dash to not lose it. To make it in time, make a very short dash to the bottom, almost immediately reverse and slow down to catch the sphere and make your way to the top.

Then There's No Time to Waste (5)
Complete Level 02 in under 15 seconds

Password: CZIHAHNA The biggest problem on your way back with the ball will be the boulder - often catching it away from you. The time limit isn't that strict - making it out from the hole is the biggest challenge here. Be very fast at the beginning, but once you get your sphere, be slow and predicting.

Efficiency Is Key (5)
Complete Level 03 in under 10 seconds

Password: QRKJHAUI Efficiency is not needed here - just time the dash right with the dissapearing laser and use the same technique from the first level. The ball seems to be able to collide with lasers and even get stuck inside.

Turning the Other Cheek (2)
Complete Level 04 without destroying the wall cannon

Password: UHEUERLS First challenge to not contain a time limit - just be gentle and this will be a very easy task.

No Dawdling (5)
Complete Level 05 in under 60 seconds

Password: MSTCTEEU Try to preserve as much time as possible during the way without ball - you should immediately use any opportunity to traverse obstacles, although there is no need to skip two laser gates during one window.

Machina Cleanup Detail (10)
Complete Level 06 after destroying all cannons

Password: PLDJENZS First challenge to utilize your FIRE button. Fly past cannons #3 and #4 before trying to shoot them. Try to destroy them BEFORE picking up the ball, as it's gravity will severly shoot you off-track. This will be the first level where you will most likely run out of fuel - when you see you are low at the end, boost yourself to the max and hope the sphere has enough momentum to go up.

Call the Rescue Team! Wait, We Are the Rescue Team (1)
In Level 07, softlock the ship in the room holding the ball

Password: AZTEZOCA This level introduces a button that toggles the doors when fired at. Shoot it from off screen while being inside the room with the ball - if you fire even amount of missles, you won't get softlocked, but it still should grant you the achievement.

This Town Ain't Big Enough for the Both of Us (2)
In Level 08, destroy the tank

Password: CABLUNGT Fly inside the tunnel, destroy the first turret and then the tank. It might be useful to do this every attempt of this level in case you have hard time shooting the button.

Mutually Assured Destruction (2)
In Level 09, destroy the tank in under 20 seconds

Password: RETOSTAR Skip the refueling station in the left tunnel, instead head directly to the right one, it's spacious enough to allow fast travel to the room with tank.

To beat the level, you will need to visit the fueling station at least twice, more if you wish to destroy most of the enemies.

If your ball gets stuck behind a boulder while you are on the top of the map, if you position yourself close to the ground, you can manouver it through the walls.

All I Need Is One Bullet! (10)
Complete Level 10 without firing more than one bullet

Password: WHIYUIOP

Perfect moment for shooting the button to open the door is while descending with the ball - it is viable to hover on the level between two homing cannons, as the bullets aren't that fast.

Just Getting My Hand on the Ball (5)
In Level 11, reach the ball in under 15 seconds

Password: ZSEDQWAV

Immediately hold the Dash and Left button to make a loop that will make you pass through the gate - this will allow you to make it for it's first opening and save time.

Toughest is getting to touch the ball - you should try to do it by coming very close to the platform and touch it with your ship's tip - this will register it without activating the cannon - you don't need to care about surviving this.

No Time for Petrol (25)
Complete Level 12 in under 60 seconds

Password: AUIOGTOI

Dash throught the electric gates on the left as soon as they open and speed through 3 cannons - don't get too low as the fast shooter will destroy you. You might be able to shoot one of them on your way.

There is a button to the right of the second tank - you need to target it precisely, as you cannot easily see if you managed to activate it, without wasting time. On your way with the ball, it will often get caught in the cannons, so watch out for that.

As the achievement title states, there is no need to stop for fuel - watch out for bullets while passing through the refueling station, as it's quite narrow.

The Shaft of Doom (3)
Complete Level 13

Password: GTBVFHRF

Here is where the challenge achievements stop and levels contain only ordinary completion ones.

This level is quite easier than the challenges you had to endure previously, so just be careful and take your time - there is a refueling station on your path, which lets you be less conservative.

Down Where the Air Gets Thinner (3)
Complete Level 14

Password: KMJIOGKL

Intented path is to the left, but you can detour to the right to take down a cannon prematurely, just for safety. There is no need to destroy other turrets on your way - you won't come back to these tunnels.

Antechambers (5)
Complete Level 15

Password: ZBNVNMXC

This level is a series of rooms. In the chamber with the fast cannon, you can slow down to activate and evade the shot from top.

Transball says: Trans Rights (10)
Complete Level 16

Password: AHDJFLLS

Final level of the game contains a mound with four chambers - before you go inside, I suggest going to the left outside and destroy the first cannon you come across - it is a pain to deal with later. Then, head to the first room on the right, pick up the ball, refuel in the bottom, push a button in the second on the right, refuel and leave through the one on the left.
