The game crashed twice during the boss fight, I wonder if it means I defeated it but I am not sure as the first time it seemed to happen quick, yet I got the minigum, the second time I think it happened after there was an animation of the boss exploding or something but the first time I did not notice that.
The game is fun. It looks very good and it's punchy with good feedback and plenty of bullets everywhere at any moment. The theme implementation is cool, I really like some of the drawbacks like enemies shooting big bullets or you can't choose between two perks anymore. The boss fight is satisfying.
You always end up with all the perks, right? I feel like there could be a few extra ones so that you don't. I also feel like during the last few waves the enemies could come faster as these last waves feel a tiny bit long while also a tiny bit easy. These are minor details.
Cool entry, thanks for sharing.
