If you plan right its too easy
Much like many other "defend your castle" and "Build your fortess" type games, it became insanely too easy towards the later levels, if you built your character right. I played through it once, as a trial, not realizing you could upgrade your attack, armor, and things of that nature. I also did not try using items... as i didn't know they existed (should have read instructions hah). I kept dying when i got to around level 7. I managed to beat my way until 10 when the enemies got fucking shooty thingies! WTF mate... I then got my ass seriously handed to me... At this point im like... "lets give it another go, this time paying attention to stuff." This time through, I played my cards right, saving up points for multishot, putting a lot into mana, buying some armor, and getting AI's. At level 17, the game was offically easy... I could sit in one place, minus when a mine or a laser popped up to hit me (or to get the occasional potion) and keep multishotting. I stopped playing because I could sit in one spot and do nothing... it was more like finger exercise then a game. Overall though, it was an amazingly well put together game. The traps were a little weak at times. Also, the armor upgrade where you use your leveling points is way overpowered. I put a total of 6 points in it and bought some armor and could sit in one spot for minutes using only like 2 potions... make it less... Also, the multishot on the enemies is dissapointing and annoying... like they should have different techniques... also variety is good ... you dont have any.
