I like the idea, i hate the game, it gives you no way to react and many times you`ll just be let in a no win situation + plus the really absurd sensibility in controls, my god!
Here is some advice:
1-Buy only level 1 of the fort to sleep
2-Buy haling station lvl 1
3-Don`t waste money on traps
4-Buy revolver as soon as possible and buy both upgrades
5-Buy Rifle and buy both upgrades
6-Buy Boomstick (i recomend not to buy the upgrades)
7-Finish to upgrade healing station
I won the game before day 4 (archivement)
Defense s OP! You can spam short shield stun with no mana ost while doing damage and blocking some lost attack,all boses are too easy with this skill...
