Whoaaa! This game has surprising complexity so far. I'm not really a mobile game player, but I can waste some time on this for sure. I like how I can move the guy by sliding my finger or tapping the screen to kinda "jump" him around. That was a good addition. I like the ability to trade up weapons and stuff. The music was also catchy!
I Don't know if this is good feedback because I don't play a lot of mobile games, but my finger blocks out my view of mobs when they get close. Would it possible to have a small D pad in a corner so you can leave the screen exposed when things get hot?
Also, what determines how fast the levels go up? I think a little more time before it ramps up would be satisfying and keep people playing longer. Not an excessively long time, but man, those mobs gang up really fast!
My high score is 245 so far.
