The art is gorgeous and you really nailed it with the reactivity as the player bumps into the flowers and other elements from the scenery. The visuals when you interact with the mushrooms are nice, but sometimes they linger for quite a while. Is it a buffering effect? The longer you sit on them, the more the effect stacks?
Gameplay-wise, I liked the variety of weapons and all their different skills and characteristics. It's a bit hard/counter-intuitive having to activate their special attacks by holding Q and then clicking. Maybe you could have Q for the left hand and E for the right hand, that would make it better. The balancing and game-feel on attacks, be it from the player or the enemies, is a bit rough, but I think that's expected. It's hard coming up with these kinds of mechanics, they require a lot of time for polishing and that's not something we had in abundance, I would say.
When I first started the game I had it on my laptop's screen, and on it I ran into the game's screen getting cut off at the sides, so I couldn't read the instructions on the menu. I switched to my other screen and it looked right. My laptop's screen is 1920x1200, which isn't a common aspect ratio, so that is what may have caused the issue.
So, overall good experience with the game, I read you're just 3 months into game development, and that's already great work, you're really good at it.
