Your thumbnail caught my eye and I wasn't disappointed. Seeing that triangle prism splitting light out through the various colours in game looks so good!! I made it through levels 1 and 2 with no issue, level 3 gave me some challenge and I unfortunately could not figure out level 4 but enjoyed what I played of your game.
Intro cutscene is a great addition as is the saving of my level progression. Would've loved a bit more of that prism colour fun reflected (get it) in the UI but otherwise everything looks great.
I will say on my first play I'd kind of rushed passed the UI telling me how to rotate so had to relaunch as I couldn't figure it out on my own. Controls work fine mostly although rotating speeds up loads at a point so I had to tap arrow keys instead of holding them. All in all, great work gamers! :)
