I see their complaints but...
Your usual art style is you, and I've always enjoyed it. Basic, not flashy, but fluid and easy to see. Which makes it enjoyable. It does get pretty hard but I think I understand that you need to get a bunch of points on the easy levels and it'll make the rest of the game easier. I do have one little complaint. The lack of health regaining. Like maybe have it slowly come back when you don't get hit or small life packs from certain objects. Cause once you got shot, you were hurt. Aside from that, I loved it! 9/10 5/5
