ok, really really stylisch gameplay, in theory. i think you should ad a text next to the + Buttons, for example something like "jump" "change direction" "run" to even let the player understand how the controls are working. i nearly quit the game before even understanding how it worked. in the end i managed to get through the first level, with a little bit of luck and 5 red rubis to jump over both obstacles.

i think if you add music, sound effects and maybe a tutorial this could be a unique game.

maybe i miss something because i did`nt finish it, but how is this matching the "underneath us" topic?

But still, well done!

I like "programmer-puzzle"-style games, but this really didn't seem to fit the theme. Also, since the "program-area" is so small, it makes more sense to add controls during the level instead of planning them ahead, which leads to this essentially just being a game with weird controls (instead of it making use of the unique gameplay feature).

I like the idea, though I don't really understand how it works. The game also doesn't really fit the theme, or have any audio, which is a little underwhelming for such a long dev time.

I don't see how it fits the theme at all. It also felt a little tedious after a while and for the 30 hour dev time I would have expected some more audio. I like the idea though and it seems quite original to me :)
