INPORTANT!!! if you are starting a game i recomend in the skill tree pressing - a lot of times it will get you to the upside downd where you can get +5 damage at a cost of 1 red gem, this is not a joke seriously, the upgrade is called "our secret", OMG i discovered that there are another 4 upgrades is the normal skill tree or the upside down that give more attack xp defense and other things they are at a long distance but is you explore you will find it
