This is so not done so don't expect it to be good, but you can use arrow keys, wad, or mobile, and it works pretty similar to zenith with the physics.
I got inspiration from zenith with the physics (sticking to the ceiling and stuff like that) I'm going to make so many more levels, the main glitch I'm trying to fix is getting stuck in the green or grey, if that happens, just click the green flag and restart, only 3 levels so far, this is probably going to take me like a year to perfect because this is probably the best and most complicated platformer, I've made, if you don't think this is hard to make, it still is for me, I still need to add music and obstacles, and like 50 more levels. BTW I'm so not done with this, I need to complete so much of it. I posted it very early because I want you all to see my progress in making a difficult game like this.
