“It sounds weird but we try to keep our innovation as low as possible,” the director explained. “We’ll say ‘it’s this game but with that.’ It takes so much time to innovate. Sometimes you find the hidden holy Grail of game design, but often indie developers sit for five years trying out stuff. We’re a studio of 50 people with bills to pay. So we can’t do that.”
I’d say try it out to see if you like the gun mechanics and movement/different classes. If you do then you’ll love the game even more when you get to the higher difficulties. If it’s not your thing, you can refund on steam if still under 2 hours of playtime.
