Really cool game with cool pixel art (but the sound is not working, at least not on my computer).
the AI of the robot is limited they got stuck when you are on a platform below them.
there were computers and plants at some places but i could not us them/pick them up
The main downside of the game is that enemies stack on top of each other and because you cant see them before entering a new "screen" (I mean a room the size of the screen) it is almost impossible not to loose some lives at some places. Because I'm not very good I could get to the yellow key but I could never make it to the yellow door :(
Also a minor issue is that if you forget to pick up the disk at the beginning you can't get it back because it is too high so the game is already lost xD
