This is a decent game but with a lot of annoying bugs and needed mods.
Here are a couple (with some already mentioned previously)
1. Up button is sometimes not accurate. cats will get stuck
2. Death glitch, you'll die but the screen pops up where you died and you're stuck.
3. I like the idea of power ups but once we've discovered it, it would be nice to know wth the power ups are with each set instead of having to constantly equip the set to know
4. the game is choppy. Even on the lowest quality settings with my 2.7 GH laptop. I can run DoTA and LoL fine without lag on my laptop but this is just ridiculous.
5. Seriously guys? an item key would be very handy
Other than that I'd give you a solid 3 stars (concept of game) with a potential 5 stars.
