I played your game on Debian 12. It ran perfectly fine with no troubles whatsoever.
I loved the graphics.
I had fun with the physics,
It was smooth on my PC.
The default game mode felt somewhat slow-paced. Since you have complete control over when the fruits fall, it never feels like you're gonna lose. Unless you give up. I liked the reverse mode. It felt like I was playing reverse tetris. But again, because I had control over when the items will fall, it felt like I'd never really lose. Have you played fruit ninja? The scary thing about that game is that sometimes you'll accidentally cut the bombs. That'd make you lose. I think that is what is missing. There are no 'bombs' in your game, no fear of failure, something that truly makes me worried about losing, makes me cautious.
The project page is nice. I liked it. Looks clear and pretty. I think your game is headed in a good direction. Good luck to you!
