Supreme job for a 7 days game! Love the visual and control response of the game, especially when you jump and crouch for the ground pound!
Here are some of my genuine reaction after the few rounds I've played:
The machine gun's projectile could use a little speed up since it was pretty hard to cartch up with a lot of the enemies while dashing and moving around! But the railgun felt very intuitive and good to use with its piercing property.
Movement feels very nice! Reminds me of Halo and Quake movement when I just b-hop everywhere though I did wish I can move faster and with more style!
Itemization is a nice spice up for your primary and secondary attacks, but it felt a little flat and generic especially from the beginning of the game when your bullet took a lot of time to reach the target, the stats felt like it didn't deserve the cool sprite it was given... But then again it was done in a very short amount of time and the feel of the game is definitely there!
I was a little surprised that the enemies actually had collision boxes when I tried to pick up the items, I thought that was pretty neat and added to the experience hehe.
The sound track slaps, and the sound design is top notch, this is overall a very nice game for a game jam!!
