note: i played until the hamster level
i'm usually pretty bad at these kinds of puzzles, but the way you laid out the levels made learning the mechanics and techniques really fluid!
i feel like there could have been more exploration of the rope/pushback before switching over to the portals. it felt like more could be explored there.
also, the enemies suddenly showing up and the game becoming turn based combat felt a bit sudden/not well tutorialized. if that's something you want to include in the game, i'd add it more progressively and give it greater focus / more levels to develop.
in the first few team levels, it felt like i didn't really need the dwarf. i think it would be great to focus more immediately on their synergies / how they work together.
