Nice little survivor game. In terms of ideas, it doesn't offer anything that other survivor games haven't done before.
Its got charm, I love the 2.5d art + atheistic, and the music was catchy. The confined map made for a real challenge if you don't have enough damage. I lost at wave 10 but had a genuinely fun time playing from waves 6+ when new and rare items started popping up. I like that I had to make the hard choice to save gold sometimes in order to get these rare items. I was sad that I didn't have enough to buy the purple item, and it makes me want to try again!
