Having see this game being developed I was really excieted to play and it definetly didn't disappoint :) This is a really solid experience! Super calming. Having the player reach a certain threshold of points before unlocking the next mushroom is a really nice pacing tool. However I think this could've been balanced a little better, I think the mushrooms that have more unique mechanics i.e. black flute need to have a greater threshold between the previous and next unlockable and some of the simpler mushrooms could've have a lower threshold i.e. slippery steps. The Pecunia is quite nicely balancced.
It works really well as an aesthetic experience I found myself planting mushrooms together that I thought looked nice althought it meant I didn't want to sell them lol!
I love the fact that some of the later upgrades / mushrooms work well with other mushrooms, some sort of skill tree that mirrors these combinations would be nice.
Sometimes it's frustrating when I can't place a mushroom although it looks like I should be able to place one maybe a little red / green glow under the cursor when placing would be nice. Otherwise the game feel is super satisfying and juicy!
