Hi there!
As we have already said, One of the coolest features in it is that you can upload your music from your own mp3 files (custom track mode).
This week, we have complemented this game mode by the opportunities to choose the arena
and the level of difficulty.
There are 4 levels of difficulty in the game:
1) Relax - a sequence of mobs is taken from the Normal difficulty level, but the player does not receive any damage during the battle. Results on this difficulty level are not considered in the leaderboards.
2) Normal - standard level of difficulty.
3) Hard - for this level the sequence of mobs is much more complicated
4) Terror - the sequence of mobs is taken from the Hard level, the player's HP is half as much and the mobs do not drop first aid kit.
