Your game is so polished!! The SPLICE animation is so CHONKY, the SFX crisp, and I love the 3s .gif that communicates the main mechanic so clearly. I also admire that your puzzles were tightly constructed but forgiving about exact positioning and placement.
If you have the passion, energy, and time for it, definitely consider releasing a longer game – I know I and many of my puzzly friends would love it. There are so many interesting twists you could take and the puzzliness ceiling is so high!!
