Your game looks awesome, this is a great setting for a platformer 😁
The feeling of exploration is nice, the map seems huge, yet I never got lost.
I think the hitboxes are too punitive, the range of the punch is so short it's hard to hit enemies without getting hit yourself. I died a lot because of this, and wasn't able to collect more than 2-3 coins without dying and losing it all. This hitbox issue can even be seen in your first gif, the one where the sausage gets killed. To me the arm should stretch to about twice its size when punching.
Getting out of the fridge feels a bit like finding a secret passage, I was expecting some small secret area and was surprised to see that's actually where you're supposed to go. It should be a little more obvious that this is where you should go.
Finally, this is not directly related to your game, it's better to zip your exe file before uploading it. I had to bypass a lot of security warnings just to be able to download it.
This has tremendous potential, keep up the great work!
