The graphics were really nice, but the mouse controls really didn't feel like they fit in with the idea of a Gameboy game. Same case with the filter, it felt more like a greyscale NES game because of that. That said, it did look really nice. The game comes off as way too simplistic to be fun for very long, and also slightly unsettling, which made me assume this was the start of a fakeout horror game at first. I feel like if you were to continue this project that might be a good angle to go with.
