I really liked the game, especially the elf not caring about clothes and not being shy since she lives in the forest anyway :)
Details I noticed/suggestions for future updates:
1) After 2nd invader (warrior) enters the dungeon player loses all of the gold for some reason, only gold you gained after win is kept.
2) Amount of the traps next to the icons would be huge help, since it's really not clear.
For example, sometimes you somehow get bomb fo free and sometimes you get 0 bombs after the payment (before the final battle of the demo).
3) For the future, just for fun: can the next evolution form of the Harpy be topless? :)
Would ne nice to keep that tradition from game series like "Serious Sam", "Allods"...
