This was an excellent combination of genres. I am not very familiar with these isometric dungeon crawler games, but I knew the basics of their combat and you certainly did a good job on that. The sound effects and music were both great - I was amazed by the music transition when entering and leaving the dungeon. Unfortunately, due to my lack of experience in that genre, I never survived long enough to bring any food back into the cafe, but I had a lot of fun playing what I did.
As for feedback, I noted that you could sometimes hit enemies through walls. Also, I think that my dungeon was generated a little off (or it could just be the camera angle) as I saw a gap that I could not fit through. But it was indeed a unique combination of making food by killing monsters. I know that these games usually do have a sort of mouse mashing combat where you just end up spamming the mouse click to attack, but I wondered whether the enemies had a bit too much health than necessary. Although, this may be a normal level of difficulty for these games; I am not certain on that as I have not spent much time on them.
Overall, it was a fun experience, even if I lacked the skill to see things through to the end. Well done!
