This concept filled me with 3 ambitious ideas in the first few moments, and that's always a good omen. This is a reinterpretation of many ideas. I got hints of Katamari Damacy, Snake, and the .io games. Pleasing enough to keep pushing on, but not frustrating enough to stop playing. Happy balance. As for criticism, I felt that there could have been a bit more juice in the collisions and absorption. A kicking soundtrack should be a boon as well! I had fun and I look forward to more.
Great concept, I would improve the UI and show visually the controls bht other than that, awesome game!
