it's funny coming back to this game in a post-Vampire Survivors world. Ok, it's more "hardcore" - you have to deal with thrust, and aiming, and enemy bullets. There are more enemy patterns and more wave varieties. The contrast reveals what vampire survivors stripped away. And as you look at what vampire survivors removed, you can appreciate what the 30 minute time limit and the limit on upgrade slots for what they are. As it turns out, I kind of prefer the limitations vampire survivors imposes!
