I have a few complaints: the light bar starts in the middle and drains too fast. Whatever I get from 2 crystals fills maybe 25% of the bar and it's not enough to even reach the enemy lines. There are too many enemies, there's no running, there are explosions even when I don't press the button to raise the lantern and some important parts of the level are too dark without the lantern. So I felt like I am powerless and have absolutely no control over what's going on. I am not even sure my attachs did any damage to any of the zombies. I suspect you are very new to game dev. Me too, frankly. I hope, you will learn fast and start making amazing games!
