wow, this instantly brought me back to the PS1 demo disc where there was the game I copy below.
I'm suprised you made differnt music for different levels, nice touch, and there's a clever level design with the rails, like "you have to be bigger to get this bamboo" so there is a specific order on the bamboos.
I couldn't get further than level 3 because I was getting dizzy, but maybe that's on me (me speaking about PS1 demos means am old, I guess hahahah)
funny entry!
