I really like the mechanic of finding new plants and using them to progress. Gives a nice Metroidvania feel to the game (which I am very much a fan of).
The Inventory menu can be a bit buggy, I managed to get it stuck in its closed state at one point, forcing me to restart. It would be nice if the menu was always open and if I could select and switch between plants using hotkeys instead of my mouse.
The dialogue text can be hard to read sometime, due to the font changing letter sizes frequently.
I also found this funny bug after dying, where my player was stuck in the tilted forward position for the rest of the game.
