To say the least, I didn't expect to play as a literal vaporwave hand even when I saw the screenshots. Lo and behold that it turns out that I'm not dreaming. Or realizing that a laser shark would be my worst enemy second only to my shaky hands.
Looking at the screenshots, I wouldn't have guessed there would be a bullet-time mechanic at all. I'm pleasantly surprised by the mechanic. I also figured out you could reload and then enter bullet-time a bit too late. I'm unsure if it was intended or not. Regardless, it helped me get a better ranking than I originally did because it gives you just enough time to dodge shots in plain sight if timed correctly. I started with a C-Rank and gradually raised what I could in a few runs. The training mode was pretty neat to get a layout of the level. If you did choose to expand upon it, I would suggest a choice between a shooting range and the normal stage as training. It was still a cool feature considering tutorials and training usually brush people's minds when initially playing a one-off title such as this.
The game was definitely fun and provided me with a challenge. I again loved the implementation of bullet-time. It's not Red Dead, but I'll take what I can get. I enjoyed the different enemy types. At first glance, I thought they were just reskins. I am happy to say that they were more than just a copy/paste enemy type. Not to mention the rat which you had the option of sparing. One possible bug I noticed was that if you keep walking into a wall after jumping, you will stay on that spot until you stop trying to move against the wall. Not game breaking, just a feature.
The visuals were rather great. Not all games can pull off the vaporwave aesthetic, but yours did. There few people that think you can slap it on something and it will immediately look good. If you planned on fleshing out the visuals at any point in time, maybe you could add hand/gun skins, or simply allowing players to adjust the color values as they please. The Dev pulled the theme off rather well.
The music wasn't to my fancy, but the shooting and reload sound effects were on point. Not much else to really say here. You kept it simple (which isn't always a bad thing).
Overall, I'm glad that the Dev reached out to me about the game. Glad I tried it out. : )
