Nice art an nice idea!
I would advice to add more effect when a key it touched: I took me some time to understand that they key I didn't hit the right key as I'm in azerty! Congrats to have created a game in one week!
Thank you so much! I definitely want to keep improving the note feedback. I also hadn’t considered different keyboard layouts, so thanks for mentioning that—once I come back to this I’ll add AZERTY mappings too!
