This idea of one jump per screen can make a really good game of puzzle/plateform !
However, I don't know if it's something I didn't understand, but I feel that most of the jumps seems impossible to make...

I really liked this! genius idea with regaining the jump on screen transitions. The hitboxes are pretty harsh at times, but wow this was cool. Nice work!

Really interesting game! It could use a bit more feedback, sometimes I die so quickly I don't quite know what caused it and I can't learn from it. 

this is quite fun!  the restriction, and how you manipulate it over the course of the areas is quite interesting!  I wish the controls and hit boxes were tuned a bit more to make it more enjoyable and a little less frustrating, but that's something you could do when/if you explore this idea further.

Love it! But damn, this spikes are punishing.
