I enjoyed playing but I wasn't sure if there was an actual end/boss or if it was an infinite game.  I got to level 20 with I think 64k points (600 speed, 1.5 bullet speed, and maybe +100 damage?) but then got mobbed on a really bad 2 skull room and lost all but my last life. Then died stupidly in a 1 skull room trying to gain some hearts.

I liked what I played and the shooting felt pretty solid. I might have preferred to feel like I was getting faster or stronger at a quicker pace.   

in my next game I tried out the cheat codes and had a really fun time with the shotgun.

Music was great but after several waves it stopped. Maybe it wasn't set to loop?

Theme was a bit weak though :)

Nice game, especially for your first jam.

Solid classic top down shooter! Got to Stage 5 and I got too cocky and went with the level with the most enemies. 

I think some variety in the power ups would be beneficial, and some different weapons to switch up the gameplay a little, including more enemy types. 

On your next jam, try to play with the theme a little more!

A good ol' basic twin stick. Not a bad way to go about your first jam, especially if you're running solo.

That said, there's not much here for me to notice. What's here is competently made, and that's commendable in-and-of-itself.
