Love that game, level 1-4 was really easy, but level 5 had me to struggle.

I think 5 cost for creeper once is to low, you can just spawn many of these in all four walls

I had good fun with the game, the 5th level was tough, always on the edge of losing! I like the vibe of the game, relaxing yet exciting! Good job on a fun game! :D

The idea of a 4 way age of war kind of game is cool, though it definitely lacks some depth. The skeleton archer seems kinda busted for the first 3 levels and then just does nothing on the 4th.  The sprite work is quite nice, I like seeing nice bright contrasting colors.
