Played multiple times, got to wave 30+ in my best run.
This is a fun game! I like the idea of slowly building up your turrets with more and more powerful modifiers. The modifiers are very fun, some of them can radically change how the turret works. This is the kind of game I would spend hours mindlessly playing. I like a lot how you can have "builds" depending on the weapon and modifier used.
I believe modifier selection is something that should be looked into. Some modifiers feel like they do little while other feel mandatory. I don't really know their impact, but you always want economy modifiers early on and having the "on kill get money" modifier leads you to only have one turrent and make it kill all enemies while circle strafing around the enemies to make time. Weapons on the other hand are weird, you only want one per turret so they kinda clog the shop when you are looking for modifiers.
This game has a lot of promise, I hope you can keep working on it.
