Congrats on making your first game! first of many I bet!
The minigames are simple and fun, i liked!
I do have 2 small feedback,
I think have to go through the vents with [i] is a bit weird, cuz its on the other side of the keyboard, so [E] would have been just fine.
I think adding a context for each minigame would improve the game a lot, right now in my first playthrough i kind of needed to guess what I needed to do until something worked.
Again, very big congrats! cool game!
