You're a Spaceman that has gotten trapped on an alien ship in outer space. complete each room and find the levers to open doors and escape to the escape pod. You can jump high. Move with WAD and press S to fall if you need to. If you get stuck inside a wall press R to reset the level. If you want to restart, press Q to be sent back to level 1.
If there's a glitch, try to ignore it and finish the level anyway. But if the glitch stops you from continuing the game, press Q or the green flag to restart. If you want no glitches you can bugfix ok?
