Hi DEM XR, I hope you allright!
Yeah, the rendering of the different colored lights looks really good, and it could lead to some cool mechanics, like a specific effect for each color, for example. I see your design intention in your thumbnail, you're not so far in-game. And tell me, the knight sprite is an open source form g-develop or something like this, no? If you want I can test to re-sprite it for a more personal rendering. When I have the time, of course, what do you think ? And another feedback I forgot to mention, the barrels don't destroy every time, sometimes you can't destoy them. And for me, the jump is too speed, too nervous (that might be also a personal thing).
Anyway, probably see you soon!
