I mean I love you. I really do.
First thing you need to do is add controller support and kick this "JKL" stuff cause it just gave me carpel tunnel.
But in all seriousness, this is cool. It would require a lot to make this a full game that doesn't get super repetitive - if that doesn't turn you off, you could legit pursue this to a full commercial release.
Gameplay - 8/10 - This is a solid base that needs tweaking + depth
Music - 8/10 - It's the right type of music for the game for sure.
Art - 8/10 -
Personally not a fan. For people who like this, I'd say it's average. However, it's put together in a very above average way that shows it was all done with intent, and that intent shows through.
Overall - solid 8/10
