I think this game is very coherent which helps to elevate it a lot. The art design, the choice of music, and the controls seem to all fit well with each other and with the main mechanic.
I find it hard to believe that you guys made this art in 48 hours, I'll give you the benefit of the doubt, because while the quality is very high, there is not a ton of variation or too many different assets, so that makes it more plausible. Still, that's insane! Great job.
I found the movement of the character with W, A, and D to be somewhat confusing maybe because the camera stayed in the same direction regardless. I wonder if it would help if the camera rotated along with the player. Also, I wonder what would happen if the movement was limited to the tether swinging only. Of course, you guys will know about this better than I will, just some thoughts :).
I liked the gameplay, but from the screenshots / footage I expected something faster paced. The volleys / airstrikes that come in and try to take you out help. I can understand why the gameplay was slower paced initially - because the aiming, movement and tether take time to get used to and so the it has to move slower, but if those things were polished a bit, I would like to see if the gameplay could be faster too.
I am not a fan of the reading-based tutorials. I think you guys did a good job with it, but even then I think a more minimalist tutorial would be nice. Of course, I understand the constraints of the jam make that a lot tougher.
Overall though, pretty great submission, largely because of how cohesive it feels.
I would love to see you rating / comments on my game too, so I can know how we did and what to improve as well.
