Demo released and some balancing

We've released a new game demo with a playable level and warriors unlocked on the ingame shop.

We've also made some changes on the balance of the game. We look forward to read your opinions about the game difficulty!

- Improved warriors attack range
- Lowered Pestilence health
- Increased teleport range by 2 meters
- Increased player and castle door health by 15%

Have fun and thanks for playing!
