Not bad, actually kind of fun. If you added some new types of enemies, different levels, and maybe some different costumes for your character it would be even better.
This game is amazing, the reason is because it is interactive. In similar games you hit the person and then just watch it fly and hope to hit a bomb or something, in this one you are trying to hit special bears and active their power which you control and you have to time rocket slams you actually get to do something other than watch. And another thing is you have purpose, you are trying to escape not fly endless miles you are always wondering what is behind each door. All in all fantastic game!
Things that should be added a name,description, and stats of tower when you scroll over them cause I have no idea what kind of towers they are (Lighting arc, Machine gun) and clicking to see their stats is annoying. I would like to be able to see penguin stats i.e Health and any special abilities in the lower right hand corner where it shows the next wave. 3. More time between waves we need more time to build.
