This is great! The gameplay is fun and the art is beautiful. The music track is quite good, if a bit repetitive. As others have mentioned, it seemed like the enemies were respawning after the player fully evolves. Some aspects of the player's shots feel like they might be too nerfed at the beginning (it's weird to outrun your own bullets), but it gives the player some real incentive to upgrade their abilities. This is really great work for 48 hours, and absolutely a solid foundation for a bigger game. Great work!
