Pretty much until the captain overseer, heal only when needed, otherwise use z and c, and the occasional v. After that, heal every battle. Go to the shop frequently. Buy armor first priority, then sword and speed. I did it and I made about 30 minor mistakes along the way, so it is possible.
Next game will feature potions and a way to track stats of weaponry (maybe).
Speed decreases your cooldown time, but does not affect the enemies. A simple way to look at it is if you have 300 speed, you will attack twice as fast as a person with 150 speed.
brennenlol: I beat it, you have to increase armor first, then sword, then speed as a bonus. The enemies will do 4 times the damage with the weakest armor as compared to the strongest.
So...me and paul are making a new version, you see. It's going to be a major rework on the current game with shops, hunting, items, and upgrades. We're taking out the graphics, for now, as the general consensus among our gamers seems to be that they suck, really badly. Thank you all for supporting the cause. May you all have a good day.
