I like the game concept overall! I like the concept of a boss fight, and it got more mechanics after unlocking more characters. The music changes depending on the current character is a nice touch.
The level design balancing is well done. I specifically liked how new character/ability unlocks are placed near the obstacles they are meant to solve, which makes the learning curve feel very natural.
I’d love to see more distinct background art or color-coded themes for different areas. Around the mid-game, I found myself getting lost quite often because the environments felt too similar, making it hard to track where I was supposed to go. But understandable for the limited time of the jam.
The starter character skill when entering a node path with multiple branches, it’s unclear which specific point the character will go to. Adding some visuals would help a lot.
There’s a specific section before the Magnet power-up where a single mistake forces the player to backtrack a very long distance. Falling all the way down to the starting area felt quite discouraging.
Overall, I like the game and the concept. Keep up the good work!
