I saw on the forum that this was the first project you put out ? Good job on shipping something, that is really something to be proud of ! :D
I do have a bit of feedback in the future if you are interested on making more platformer games ;
- Focus on a core unique mechanic that you can polish
- Avoid leap of faith
- Make the camera look in front of the player rather than what is behind them
But honestly, my first few games weren't half as good, so well done ! :)
