Hey! I really liked playing your game. The visual effects and music add a lot to the style of the game, the sound effects made playing the game feel satisfying, and the puzzles are simple to understand but clever. I especially loved the 8th level (no spoilers!)
All of these, combined with the polished interface (settings, pause menu, etc.) made this game a feel like a complete package to me. Huge props to you and great job!
