The artwork and the main character is really adorable :D
The game itself is fun and it felt cool to "go full Sonic" with walking + blasting fireball without a stop, not sure that was an intended feature or not :D
The music is really-really kick*ss.
The face like rock/hole patterns on the background hills reminded me of Mischief Makers (almost everything had a face or at least something reminiscient of that), and old N64 2.5D platformer I've absolutely loved back then.
My only complain is that there were no landmarks or anything to really differentiate between specific parts of the map which made it a bit confusing to navigate.
