I loved seeing all the different enemy types, especially the ones with little telegraphing or attack animations. I only wish all the attacks were animated like that!
Some of the visual design, especially the text and backgrounds, could be a bit clearer. Some backgrounds were a bit visually overwhelming (stripes), and the dark background obscured the health bars of enemies. The placement of the secret region was a little hard to discern, I thought maybe you had to punch the sign or each of the dummies? But I did find it in the end. Impressive work for one person and a first jam!
