Hey!
Nice game! just played two rounds.
I liked the concept and the success sounds and feel.
I would add an option to "regret" and take back a card i already placed on the right side.
I would also add a "Shuffle" option in case i don't have other options to finish the level with the existing cards on the board.
To your question - the game is fun and challenging.
I’m also looking for feedback on a short browser game I just released, Toy Box Challenge. It’s a 5-minute physics stacking game and I’m currently looking for desktop + mouse playtesters. If you feel like trying it, I’d really appreciate your honest first impression:

Good luck!
