I have idea how you could do brakes. On android when player push both steering buttons then a car will brake.
Got a bug with transparent image of cars at cutscene
After update to version 2.1 Its much better, but i think enemies should not shoot at player when they are out of render at least those hitscanners. Zombiemans.
Also a good addition would be possibility to run this with original wads. If you also could do something with invisible doors, maybe indicate them with a symbol that will popup at different layer than door, when a player is close? (Something simple, triangle maybe?)
This can turn to another yet very different port of doom. It needs polishing but it is possible.
It is a great idea but at the moment this game is unplayable, due to range that player can see. I made a screenshot that show player range, the stereogram on my image is Cross eyed.
Right now enemies can spot player at too great distance so player doesn't have any chance with them.
If you check files there is folder "scripts" and inside should be file called "gen_GenerateSprite.gml" This is where my generation algorithm is allocated. You can open it with notepad++ if you don't have GMS. Everything is well commented if you will have problem in understanding anything then ask questions here :)
This tool can generate pixel-art style space ships.
First steps to use:
