I enjoyed playing it!
The only thing I didn't like (and maybe I was doing it wrong) was how fast your multiplier would reset. It felt like I would spend ages building up a multiplier, just for it to run out after like 3 shots, which didn't feel satisfying. It would feel so nice to build up the multiplier, then be able to destroy a whole group of enemies!
Other than that I did really love it. Sound design was amazing!
