I incredibly adore this game! this game has great music, good graphics, (if your into 2D graphics that is) decent story line, and just amazing overall. This actually could have a chance to become like a real game!
Anyway, amazing game, i'm going to be playing this game a lot, the only bad thing about this game I found was the fact that it takes awhile to really understand how to "play" only because the auto given keys are kinda strange at first but after awhile of playing the game you get them down pat, but amazing game loved it and bye!
(btw I do know that you can change your keys in the settings)
We're already becoming a real game - we just released on Early Access: https://store.steampowered.com/app/876650/Aground/ , and we should have the full version out next year!
As for the controls, everyone has different controls that feel comfortable to them, so I included the option to change keys so that people could use what they liked best, and the defaults are just what I personally like best (I'm weird).
