Functions well, nice work!! The sound effects definitely add a lot, and I like that the towers get attacked back. I think the addition of some story elements would help to set it apart more from other TD games, but it's a very solid base. Good job!!!

Got until wave 9, the restart button is quite useful for when you loose all money, maybe showing the building cost in the upgrade screen could be nice so the player can see if its worth it. Well rounded overall!

This is a really neat tower defense! I really like that the enemies target you back! It helps keep the game from turning into an idle game once you get the towers in the right spots. 

The random tower placement areas was also a neat touch! Helps make each run feel a little different, while still using the same map. Best round I had, I had 3 placement spots right by the start of the road, so I was able to whack them right as they came out the gate!

Great job overall! The art and UI were super clean as well. Well done!

Like the numbers to show health, good idea. The upgrades, simple but clean gameplay, placement of assets, and different enemies and upgrades help to make this pretty fun. Nice job on it!

I liked the upgrade system.

Real nice simple game. Sound is too loud tho :o

I liked your game, the art is beautiful as well, good job :)

Cool spin on tower defense genre! There aren't many that has enemies retaliate back at you. Good job!
