I've actually found it better to just not use the boost at all. Ever. Or at least during the later portions of the game. Spent 5 minutes to get 500,000 distance in one run then quit but then used nothing at all, afk'ed and got more than 750,000. Just thought I could help
Some how when following the tutorial, the tower I placed did not attack the monsters that attacked me and I am stuck without a tutorial and no way to advance, I really need help
Over all good game but many glithches such as 499 agi is instant energy and after all skills are maxed the tourneys glich you to have no energy or gain of energy. I would like to see this fixed 4/5
