Nice work on your game. I like the choice of colors and i was looking forward to start playing right away but unfortunately, the game wasn't fully playable for me. Things like level design(spawning the platform ahead), win and lose conditions, pause are among the key areas to look at for further development.

Well done for your submission. 

I had a few issues:

1. I couldn’t jump well and when I fell, my character did not die. I do not know if this is by design
2. After the first jump, I could no longer jump again.
3. I got stuck at the bottom of the screen and I couldn’t make progress
4. A tutorial would have helped me understand how to play the game, and what my objectives/goals are
5. A suggestion: introduce enemies later on in the game. Players should get comfortable with the controls first

Thank you for your submission. It’d be great to play an updated version.
