Really awesome job on this, it's very impressive that it's created in a custom engine too. I love rhythm games so I had to check this out! I really enjoyed playing it, but the shift mechanic to raise the pitch of notes felt super hard to execute. Only the left shift worked for me, so doing raised notes on ASD was pretty tough I would've liked to be able to hold the right shift instead in certain scenarios. I think I would've liked having shift to raise the pitch be a toggle instead of having to hold it too. Overall tho I really enjoyed this game, I liked the songs and it was really fun to play. Great work!
