One of the best games I have played considering the submissions!
Perfectly designed levels with a basic and understandable logic behind them. The few levels, in the beginning, teach the game mechanics very well. I enjoyed every single level that you have created.
Visually, the game has just the right amount of detail. The color palette and the overall art style are just on-point. The audio does not bore and lets the player concentrate on the puzzles. The resolution restriction also seems to be gracefully handled!
Also, our submission has certain things in common with your game. Maybe that's the reason I liked yours this much, but still, I think it is an awesome game that you've created right there!
Adored it, well-done!
