Feedback (from Nicholas):
-You still run into the issue where if you place mushrooms at the exit point there's no way to refresh/take down mushrooms and it softlocks the game
-I still think you could increase the difficulty a bit by stretching out the different puzzle mechanics. In some ways, you introduce the omnidirectional mushroom too early; it should exist within another biome or level.
-I think currently there's a bit too much trail an error, which can be fine, but I feel like I can't tell if I'm being punished for starting over or retrying things over and over.
-I think some mushrooms could benefit from being moveable or being "rooted." This could make the learning curve a bit more smooth so that there's a lot more "forgiveness" early on with how players choose to place their pieces.
-Some spore colors might want to be modified because it's hard to see when some have one spore or two (especially with the white spores), maybe even just a simple outline to help me clearly see that against the animated sprite.
-Really great loop idea, iterate on it more!
