So I wanna preface this by saying that I was a big fan of your guys' work in GD when I played from 1.9 to about a year ago, when I stopped playing. I happened to catch your submission in the GD discord by complete luck since I was still in it for some reason, and knew I had to give it a review. Hopefully I can remain as unbiased as possible when writing a review that I know some of my favorite creators are gonna read.
First off, the art is overall pretty great. The "juice" is just right, not over the top but still satisfying. The art style isn't unbelievably unique or original, with the white on black palette being used quite frequently, but it fits the game well and its not just straight lines or one shade of white. Everything is textured and detailed.
In a rhythm game, music is crucial, and I almost have trouble believing that these tracks were made over two days. They're honestly fantastic, with the gun's firing noise acting as a driving bass. Something especially interesting is that the BPM actually affects the gameplay, so the tempo must've been chosen ahead of time. I can see how the game could get really in-depth with songs that slow down or speed up at different times, causing the gun's fire rate to change. And since the game is an auto scrolling rhythm game (hmm, sounds familiar) you could still handcraft the levels based on where the song is at all times.
Gameplay-wise, the game is what you'd expect from experienced level designers. It starts out with a tutorial teaching the basics, accompanied by an ambient track to keep your gun from shooting. This ensures that the player isn't overwhelmed with information when the music starts. I love how the white dudes get more and more dense over time, so despite the game essentially being one long level, there is still a noticeable difficulty curve. One section is particularly awesome, with the cracked blocks on either side insuring that you can only shoot the walls once before they become hazards.
Overall, the game is great, and I wouldn't expect any less from this team. I can tell a ton of work was poured in. Fantastic job on this entry, and I honestly can't believe it doesn't have more ratings.
Also if you guys have the time, it would really mean the world to me if you were to play and rate my game, as I like to think that it implies a lot of design elements I learned from playing GD and similar platformers. That's it, take care y'all.
