I usually don't play games like this, but I think it was easy to understand and looked great as well! I personally feel like I didn't need any upgrades, since I mostly just dashed through the enemies so I think it was a little too easy, but it was still fun and it was fun to see all the different enemies you had done as well. I also don't think there was any scaling right? I played for 5 minutes and didn't really notice it get any harder
