Hey, you asked me to look at your game so here I am.
First of all, the polish on the graphics and visuals is kind of crazy. I love it. It made the game feel professionally done, which I really love. Nice job, there.
The gameplay was alright! The amount of gravity on the character felt a bit weird, but I got used to it and I think it worked well for a completely vertical game. I enjoyed each room, although a few things felt janky. One big thing was the soliders - I got hit by one of them once because he fired a shot just as I jumped on his head and it hit me as he died. This was because soliders don't appear to stop shooting when they can't hit you and instead the bullet just goes into them and disappears. That seems slightly weird.
Also, the grabbing mechanics seemed a bit slippery and weird at times. Sometimes it felt like I should be able to pick something up (like a solider's helmet) but was unable to. It also felt like when I threw my stuff at an enemy they wouldn't die.
Finally, there were also one or two times where I nearly softlocked myself because the jumps were almost pixel-perfect after you removed a box or something.
I say all these nitpicks to the gameplay, but in reality, it was quite good. The mechanics were simple enough for the purposes of a jam, but complicated enough that things were fun.
I liked the fact that you were clear about how your game fits the theme and its inspirations. It was a nice read. Also, the presentation of your game and the itch.io page for it were absolutely phenomenal. Nice job there.
Overall, the gameplay could use some polish in a few areas, but the overall mechanics are solid and the graphics/music make up for most of the deficiencies in gameplay.
Nice job!
