Hi,
nice game, played and rated. Missed some sound. make 1 or 2 extra layers with a background and parallax. Also, make some things (clouds-birds,..) spawn at the right of your screen and fly to the left. Tthis would be a big upgrade for the visuals and will make the world look a lot more alive.
Please feel free to try out my game and rate it here: https://itch.io/jam/cgj/rate/474542
Many thanks,
Kris
