Hey there! On first glance your game page looks really neat and intriguing.
1. No :/, but then again, I'm not good at platformers.
2. It started out well, the mechanics are well explained, but that tight corner with the spikes was a little unfair haha. The platforms are also well spaced, so I think the second part as you said is a little tricky.
3. I really like your color palette and the art. Todi looks intriguing. Also, nice animations.
4. As stated before, level design could use some work.
5. One thing I'd add is a little bit of background art that give a little bit of exposition about the world (coz world-building adds a lot of character to your game). Also, adding a different sprite for the downward part of the jump would be a nice touch.
6. The game mechanics are well done.
7. No bugs as far as I played.
All in all, quite an interesting looking game. Would like a more accessible design for noobs like me :P. Have a nice day!
