Thank you very much for this comment !
I created all the graphics myself, and I opted for a minimalist style due to the limited available time...
I'm glad I finally took the plunge and submitted a game for a real game jam.
In fact, this is also my very first game that I've dared to share online.
Comments like these almost make me want to share all the other little game snippets I've created in the past that never quite came to fruition...
PS : Were you able to progress through the levels despite the fact that the jump can be held continuously ?
