Just got out of a final exam and played this. Honestly had so much fun and it cheered me right up! My face was literally :D the entire time!
I will say though, 'A' isn't the most ideal key to use in my opinion. It's kinda awkward and not very right-handed friendly. I think spacebar would've been a better key to use.
Aside from that, honestly fire game! I LOVE the concept and the music is awesome! If y'all release a full version, I'll definitely be among the first to get it- no joke. Amazing job you guys!!
