The enemy designs are so cute! And the player for that matter. The combat feels fair, and you can route the enemies into a train like in classic COD zombies. Unfortunately I think I am a bit lost in how the upgrading system works. I was gathering the upgrade points, but is almost like I was combining things incorrectly, and my attacks never got stronger. I think it would be help to give a quick explainer of the logic of the upgrades.
Overall very cute and stylish!
