Really clever puzzle concept. The main mechanic with color combinations and portals are great! The aesthetics are also captivating. Well done!
The level design needs a bit of tuning at times because you can easily get traped, not able to backtrack or going anywhere at all. I'm sending you 2 examples I ran into. At the first screenshot: if you miss the arrowed collectable you cant return back and in the second one: you are completely traped xD
Overall, this is a wonderful entry! The level design is already too deep for the time you had so it's really impressive! You should definitely keep working on that gem! Congrats!!
