Nice, but much too diffecult =S
This game was way too hard in my opinion. Is it even possible to get to a high level? I didn´t got further then level 3. In the first level I was able to survive quite easily, but I still had taken some damage on my wall. I lost my wall in the second level, those lava guys had too much HP in my opinion. I couldn´t stop them before they reached the wall, even when I hitted them with about 4-5 shots. Then they came for the Tesla Coil. I was able to stop the first one, but there´s always about three on the field at the same time. Please make this a little less. I couldn´t beat level 3 cause those spearman made it much too diffecult and you had to defeat dozens of them before you completed the level. Please keep them out till level 10 or something.
I was also unable to buy any good upgrades. I buyed a lot of faster reloading, but this didn´t helped much. You just don´t get enough cash in this game. Either make the upgrades cheaper or make us get more gold for defeating enemies.
As for other stuff. The graphics were pretty nice, but the enemies didn´t looked that good. The background could also use some trees and stuff like that. I didn´t liked the music much, don´t think it suits a game like this and it was kinda depressing somehow. A different song would be nice.
Overall 7 out of 10, 3 out of 5. It´s really a shame that this game is so incredibly hard. But I´m sure it´s not much of a problem making it a little easier. Anyway, keep it up and good luck with your next flashes.
