This is great! I wasn't sure what was going on with the screen select starting off but soon as it made itself obvious I was sold.
It's such a clever idea that would be so easy to mess up but while I never felt like I mastered the multi-screen I did have a lot of fun with it.
The gun play and movement was satisfying and the music track was very fitting.
The enemies don't quite fit the environment but they fufill their current role. I really appreciated the lo-fi level.
There's definitely room for polish and expansion but an absolutely solid base.
(also I found the 'You shouldn't be here' cat photo, the fountain in the middle of the second(?) arena is real easy to launch off of and get out of bonds.)
