Bad, even by "retro" standards.
Didn't really appeal to me. The graphics were ugly, the music was too basic and grating and the controls were pretty sticky. I understand that recreating an old Gameboy Colour was the idea and you certainly accomplished that.
But the Gameboy Colour sucked. It sucked hard. It was an awful console. Perfectly serviceable in its day, but did not age well. No way in Hell.
Combine that with the pretty soulless character, setting and gameplay and you get...a generic Gameboy era platformer built in under a week with no real features to help it stand out from the crowd of other retro pixel games. This wouldn't even have flown in 1998, on the Gameboy Colour, because there were better games even then. Lord knows there are better games now.
