The art is super good! Everything felt pretty smooth. I loved the concept of the game! The enemies seemed a little interest as the could pass through the water and you couldn't. I also thought the moving platform went passed too quickly. Instead of having just one, I would have liked to see 2 of them moving slower!
I didn't understand the placing blocks. I did not know 5 and 6 buttons did. A little tutorial would have been nice!
The map seemed to be a little to big for a tower defense game.
The music was a really good! I was jamming a little while running around the map!
I noticed it was incomplete so I hope you keep working on it! Really good job!!
