I like the visuals of the game. The pixelart is cute and in general I'd say this is a solid entry for the Jam. Good Job!
However, there are a few things I'd like to give feedback on.
As many others said already, checkpoints would be a great addition to the game since it is really punishing without it.
The enemy speed and positioning could be improved on. The Teddy for example is way too fast, which also in turn leads to a bug where they disappear from their paroling place. It is also difficult avoiding them in smaller places since your own character isn't that fast. Yes, it does challenge the player and makes it more difficult but it makes being hit by them especially salty considering there are no checkpoints. It's cute tho how they turn into a plushy after you touched them.
To wrap it off, again, I like this entry. Well done!
