I really like the flower enemy that shoots multiple projectiles! It forces me to play a bit more carefully and it's not too easy or too hard. The game itself was pretty fun too. For a metroidvania, I think there could definitely be some branching paths. For example, after getting the dash, the path forward was still linear, so you could probably tease another pathway that requires the dash to progress beforehand. The boss at the end was really cool, I liked the animations! I think it could use some more clarity on the attacks though, and less enemies that spawn since they tend to be more distracting rather than adding to the fight (I ended up just ignoring them and focused on the boss). I also think some more platforms to maneuver during the boss fight would improve the fight a lot since it would give more options for dodging.
Otherwise, you have a nice variety of enemies and gameplay was engaging! Congrats to you all!
