Woah. I thought this would be pacman with bottles in the four corners. The more bottles, the wobblier and then it would be a challenge to make sure that when you hit the fourth bottle, it's your last one because he'd be "drunk." I was wrong.
Love the animation work on changed towers, hits, critters. Sounds good. Big jumps at certain points (wave 3 is one) that are challenging, perhaps impossible to completely defeat creeps in those wasves. I respect the work done here.
Good start. Spelling errors. Grammar errors. Battle system is too simple. Story is good. Numbers of hit points should be displayed where the damage takes place, and the hit points are hard to read right now. But good!
