Really really really impressive for a 10-day game project made by one person. Honestly, it's impressive period. Movement feels good, art is charming and vibrant, and I loved the twist with the boss fight at the end. Only really gripe is that the controls are kind of awkward with keyboard.
Also, seeing the title screen with the subtitle "edge of isolation" with a cute smiling cartoon character staring at me made me crack up. Hilarious.
