Great game. Reminds me of MegaMan and Cave Story. I love the sounds, I loved the challenge. I could never get the second cheat, but I did beat the game. The way you respawn when you lose health is unique, so they're more like lives. In any case, for a game jam game I would have preferred to not respawn for taking damage but only when I run out of health. I really liked the retro looking art, and I liked the platforming. But the moving platforms were a bit glitchy (acceptable for a jam game, I didn't mind). Overall I liked this game, I even played again to try and get the second cheat, but I never did. Great job!

edit: oh and I didn't like the controls, using both mouse and arrows and space was a hassle for me,  I would have liked if up arrow jumped to get rid of needing the space bar. then you just have mouse and arrows to worry about. I didn't mind Escape to pause though, since I rarely needed that after memorizing the cheats.

I hope this is the type of feedback you were looking for!

Nice use of the limitation.

It would be great if you could recall the last command by pressing the up/down arrow like in traditional terminals.
