Hi, I already gave some feedback in the discord server, so I'm going to summarize and maybe add some new things that I came across.
I do really like what you have so far in terms of the museum and fungus level. However, a new issue I came across while replaying the game is with the enemies spawning randomly in the fungus level. There were times where I was swarmed by 5-6 trash monsters upon starting the level, with two more running towards me when I defeat a few. While I was able to last longer thanks to the enemies dropping health ups, it gets really annoying to be dog piled by enemies just because of they somehow spawned close to each other. There was also an instance where an enemy spawned inside one of the piles of garbage, which made me unable to finish the level due to not being able to reach the last enemy (look at picture to understand what I'm referring to). I also came across a glitch where pausing the game somehow disables the dodge roll.
As for the visuals and animation, most of them are well done, but it's hard to see the main character's due to much of him being obscured by the mushroom hat. Speaking of the mushroom hat, I noticed that part of the model is stretching, which is shown in another of the images. I also recommend adding a loop to the idle as the child just freezes after a bit.
Aside from that, I still enjoyed your game and can't wait to see the next two levels.
