Thank you so much! That collectable is kind of unbearable, I won't disagree, I like making players work a bit, but that one's not my proudest design haha. I'm glad you enjoyed the rest, especially the music, I hadn't made any music before this game, so this was my way to motivate me to learn it. I almost removed it before posting the game from a lack of confidence, so I'm really flattered you like it!
I noticed you have a game too that looks insanely cool on this site, I'll be trying it real soon!
