How did the experimenting with the animator state go? It looks like a succes!
Sadly no audio to accompany the simplistic but great looking visuals. Your gameplay setup is done very well except that I suggest raising some walls up so you can't jump over them and need to use the punch ability. Overall a great game but it could use a little more polishing as expected for a 3 hour game jam. I myself would have wanted to spend more time on polishing as well.
If you could spare some time I would love it if you could take a look at my submission as well and leave a rating!
