Great graphics! I really liked the flicking between semi-dungeon-crawler and tower defence. The speech was also very funny! I also liked the music for the separate locations, that was a nice touch! The tower defence mechanics also felt quit polished!
I was able to buy everything in the shop instantly, not sure if that was intentional. The UI in the menu also looked a bit off, might just be to do with the resolution though, it wasn't a big deal though!
Overall, I really enjoyed playing, and this is a great entry!
