The game is in dire need for balancing. One basic turret is enough up to the 5th wave and I could place 3 turrets in one corner. Menus are neat! Simetimes buggy, I could hear the sound of choosing a turret behind the upgrade menu. 

Maybe scaling up with the upgrades would help the game fit the theme... Or something else. Right now it's Ravine with different upgrade menu.

Couple of points:
* You can buy chips but not be able to place them

* It would benefit from having a speedup time button since I was on like Wave 10, but nothing was challenging me to scramble to put stuff down and build defenses

* it would be cool if the chip-upgrade grid would get bigger, ie scale up

But otherwise, great presentation and functionality

Quiet a few bugs here. Balancing of the money is also a bit off. It is way too easy to buy stuff. The beginning feels very slow. I'm not sure, if the waves get harder.

Overall a nice idea to have the upgrades of the towers be modular. It does not feel much different from a basic tower defense game though. A bit more polish and features could have made a lot of difference. That you for you submission!
