What a polished game, I’m impressed! The game is gorgeous, and the idea of the world being filled in as you get more colours is inspired. I like the idea of the colours being used as indicators for where you can use your new abilities, though sometimes perhaps done a bit too blatantly.
The healing system is simple but effective, I like it, it works quite well at rewarding consistency. It did make the platforming sections feel a lot harder than the enemy sections, but perhaps that’s intended. I found the room with the moving horizontal pillars the hardest section of the game, but not in a frustrating way, it was a fun challenge to learn to overcome.
If I were to deliver some criticism, I’d say that aside from the stellar presentation, the game itself is good, but a bit standard. I’d have liked to see a more novel upgrade rather than the standard dash, wall cling, double jump, maybe something tying into the colour theme? But perhaps that’s needlessly lofty. Overall, you both did an excellent job, great work!
