Okay, played this game and find it interesting being one of the 3 2D platofrmers in this jam that I played so far (including my own for the jam) and this one is alright, reminds me a lot of Mirror's Edge, probably because of the white buildings and different colours to mark on what is different. the gameplay controls is good, could be better with alternative controls.
I do like the idea of having to reach the top while the bottom is slowly trying to kill you, though I don't see it with the theme of Solarpunk, I don't know why the player character gets hurt by nature, makes me wonder why they are planting the seeds if the plats is damaging to them, a bit of mixed messaging here.
Lastly I don't know if you include it, but I can't hear anything, no music, no sound effects, absolutely nothing. not sure if this is a bug that no volume is being played or if you just didn't add any. if it's the former, just letting you know, if it's the latter, it would be nice to hear some stuff especially when they can be good indicators and help with the visuals.
Overall, a neat game.
