This was pretty amazing, I loved all the parts you can use to upgrade your own cute little organism. There were parts where I got a bit stuck but it wasnt too hard to find a whirlpool to the next level. Boss battles are fun and I liked that you can use the environment to your advantage (hiding behind spiked balls or behind plants) also you gain a new part from defeating bosses, opening up more build variants. Great game!
My only suggestion is more detailed stats for each part such as how much speed it increases as well as turn speed stats or how much damage the part deals per hit or something
