Wonderfully amazing! Is there anywhere I can donate to support you? I feel a little guilty getting to experience this for free.
Thank you very much! Don’t worry about donating, I’m fine financially. I intended this as a free game, your comment already makes me very happy! :) If you still want to help, you can always share the game.
Amazing game! This is what it feels like to discover a really hidden game design gem. I spent hours choosing my fav combos for each field after finishing everything. Perhaps 'tool puzzles' will become a new genre one day.
My only nitpicks in v1.0 are (ROT13):
One of my favourite games of 2025. Looking forward to your future games!
Woah, congratulation for getting this far in the game! :D You’re actually the first player I’ve heard of who solved the advanced puzzles. This means a lot, thank you very much for sticking with the game.^^

J'aime trop tes jeux à chaque fois et celui là fait pas exception ! Je pourrais rester des heures à faire bipboop dessus
Merci ! :D Je suis très content que la musique plaise.
This is amazing. It took me a bit to understand what was going on, but the experience of stumbling through learning was so groovy and pleasant that I didn't even mind. This game made me someone like me, who hasn't touched an instrument in decades, feel like a brilliant DJ. Very cool! Thank you for sharing!
