Really struggled to enjoy this one unfortunately as the concept is clever.
Backtracking in games needs to be designed well or at least fun and faster to do using something like shortcuts but walking between areas was a slog. With no explanation, I wasn't sure if I was meant to workout puzzles or unlock them later which I eventually started to do, the pallet swap was unique and matched what I was hoping for from the game but I think it could have been utilised to craft harder puzzles and unlocking the rope mechanic felt lackluster as I'd wanted that from the start so saw it coming, my reaction was "Finally." rather than excitement for a new mechanic.
I can't say I was able to beat the boss fight, starting down the tunnel and having to walk the way back up slowly every time I grazed the box, which moved seemingly unpredictably (obviously connected to the colours but hard to track), was frustrating and ultimately led me to calling it quits without figuring out the boss fights puzzle.
Like others, I fail to see any connection to the theme as you don't "count down" colours...
With some more feedback for the player, less back-tracking and maybe even just a sprint button, I can see this game being a lot more fun.
I did play a small section of this during a late night stream but was too tired to solve puzzles so returned today to play again and write the feedback. I hope you can take this constructively as I do really like the concept just think it misses a few notes. It did look nice, especially the shadow following the player, and seemed well put together considering it is a jam game.
