Really good. I like how the scope of the game was clearly defined "survive 7 times and become cleansed" was a great statement. I also enjoyed the energy it had - things attacked fast, moved fast, and generally felt much faster and more fun than many other crawlers can be.
The balance was really good. I had the option to heal, I pushed my luck, I got a TPK and then tried again with a "run to the cleric" a little earlier. Very nice.
The store completely confused me. I clicked on my weapons and they went away (sold I assume but I didn't find where my currency was shown). I never figured out what to do here other than see my items in place.
Making it an auto battle was a good idea I think, really worked well, but I couldn't tell what each individual characters' damage was because it went by so fast. I would like to be able to slow it down a bit.
Overall a very nice entry.
