I loved everything about the game. The sounds, the story and aesthetics are really good. Some feedback:
The game seemed to lag a lot for me, I didn't understand why.
I had to reduce the DPI of my mouse to 600 to play it, the camera is way too sensitive.
I got stuck and wasn't being able to find the second key on the third stage, but I saw the video Crashin' Thrashin' Seranatis linked and managed to clear it! Good job overall!
