I really like the idea and I also really the presentation, the art and the sound effects fit well with the concept! But I also gotta say it feels a bit too repetitive and seems easy to cheese. Overall it's still a good game!

The core idea is interesting! After losing my first attempt, I realized that the game was much easier to just cheese, and I just clicked the first option as fast as I could repeatedly until I had defeated all 100 adventurers. I think there could be some very interesting ideas with adding the occasionally unique hero who return and can only be defeated by very specific conditions that you need to hold on to. Maybe characters that survive come back strong and with more resistances? Also, the dancing is obviously funny. Nice work.
