I like the way you mixed genres/gameplay, have some dialogues and a story, and divide the game into different sections.
Having said that, the gameplay itself is rough and doesn't feel right. I'll spare you the details, cause you probably got this a lot.
The sound effects are a bit loud and annoying. Graphically, the artstyle lacks consistency. You have some nice explosions and effects (the pool shader), but they don't fit too well with the other parts. Animations are too long sometimes or get cut short, enemy shadows aren't below enemies, hit effects are too small to be readable and don't provide much feedback (and there's no hitstop, screenshake, or something else in place of that).
It's a complete game though, and that's a lot. I played it from start to finish, which says that even with those flaws the game interested me and managed to surprise me. So good job :)

Overall, an extremely hard game in the platformer part, in part because I'm terrible at platformers, but mostly because the slopes not being traversable really limited your options. I liked the multitudinous enemies and so forth. One thing I think it really needed was a bit of subtle music playing during the scene so that it could bring the spookiness to life. I really liked the game over all though, good work! Bonus points for Godot!

Good job! You've got an impressive amount of content for a jam game with three different minigames!

As others mentioned the controls don't feel so great in the platformer section, it's hard to go on slopes and for something that needs precise timing to avoid falling into spikes, that can be a bit frustrating. Similarly the attack animation doesn't really show the range of the attack, so most of the time I ended up bumping into enemies (thus losing health) before I could land a hit.

Still, it works fairly well and I could beat the game! 40-something Zombliens in 50-something lives :)
The artwork is fairly good,  and contrarily to others I didn't struggle too much finding the items (I avoided Zombliens since they would easily overwhelm me and kill me in 1 s, as there doesn't seem to be a grace period after a hit so they accumulate).

I had a good chuckle with the story :D

Hey — I found all the items! That level was really, really hard. Also, the bird in the beginning wrecked me more times than I care to admit. But all is well now. I killed 62 Zombliens and I only died 118 times. Good job!

Nice graphics and atmosphere, but the controls are very slippery, the character is always sliding like hes on ice the whole time.

I died 37 times before I had to call it quits. The level where you had to collect the items was too difficult for little ol me. The zombliens overwhelmed me every time...It was a fun experience though.
