I really love this game and I really, really want to see more. Like others have said, a stage select and level designer would be nice. I'd also like to see a mode where you can continue in a single stage until a certain point, or at least the ability to see how the two wrestlers will continue to move after scoring.
There should be a way to order units to prioritize certain enemies like flying/non-flying, ones that are being attacked by soldier/ones that aren't, stuff like that.
Ok, obviously this was influenced by Touhou Project, but I'm really annoyed by the people saying this a copy of Touhou Project.
Some things this has over Touhou Project
More variety in characters: The characters all have unique attacks and stats, and they seem balanced.
Sub attacks: I thought this was a neat addition that added a little more depth to the game.
Store: Not much to say about this.
Some things Touhou Project has over this
Better music: Not that I expect someone to top Zun's music anyway.
Better bullet patterns: Touhou Project had bullet patterns that are fun to look at and navigate. Here it literally looks like a bunch of shit is being thrown at you. This is probably my biggest complaint.
Overall, it was still fun.
I would like it if the evolutions that made you invincible to certain attacks would make it so that those attacks just didn't show up so the screen would be less cluttered.
