Classic and cute platformer. It reminded me a lot of those classic flash platforming games you used to see a lot in the 2000's on Miniclip and such. I think you've hit the tone well. You can also tell that you have spend a lot of time testing and adjusting the levels in order to make it possible to jump at the right times and in the right places. That is really great, and helped make the experience a bit more smooth. The music was a bit sad, which really got amplified each time I died. I really felt for the little jungle adventurer.
I hope you've had a good time creating this game :-)
