Loved the walking animation =D It's a pretty solid base for a tower defense game. Enjoyed playing it and especially, the end game bloody shooting looked fun.
What could be improved: balance - not much challenge after you buy the first idle cannon; shoot on left click would be more familiar; drag to switch the view is a bit of a strange choice - it would work really well on mobile but for pc one click/key press would be more user-friendly; definitely put that walking animation to enemies as well =D
Appreciated the ability to win. Very well done completing it in just 48 hours!
