This an incredible game! The problem is that its way too hard at the start and the only instructions you give are in the description for the game. Because of that, it took some time before I realized how to even get the guns working (then again I'm not too bright lol).

First off, add a basic tutorial.
It doesn't need to be a lot, just an explanation as to what the aim of the game is and how to get started placing weapons.

Second off make it slightly less difficult.
In my time with the game (which was only like 10 minutes, I found the only effective way to get past the first wave is to have 2 railguns and a flak gun, which cost most of my money. It really bothers me that I have to spend most of my money in the first wave. Maybe make the flak gun more powerful or make the tier 1 railgun cheaper.

All in all this is a really good game and you should be proud of what you've made. Great Job!

Combining tower defense style mechanics with having to balance the guns on a see-saw is really interesting and unique! But I would really like it if I could see the bullets shoot out from the guns as it's quite hard to understand what is happening during the wave. Besides that, the art and sound are really charming, great work!

The game is nice, but not polished. The platform sprite is a stretched out unity sprite and the balance is way to intense. I was barely able to pass the first wave and you give me a single gun worth of money? Brov
