I've decided to try using a standard format for all my feedback this time around. Please excuse me if I come across as overly curt or miss something important about your game. I'm writing these all quite hastily as there are a lot of games in the jam this year!
What I liked
The graphics. They're dirt simple, but charming.
For the most part, the gameplay. It's a simple top-down shooter but it's time-tested and it works.
What I didn't like
The difficulty.
I wish it had some story because I like story, but I'm kinda on the fence about this because it's not strictly needed.
Did I think it was so bad it was good?
No. To be honest, this one frustrates me, because it would be a charming little shooter without the insane difficulty. The graphics are simple, but they have tons of charm somehow, and aren't bad at all. The sounds could be a little nicer, but with the graphics the somewhat lo-fi sound works. The gameplay at its heart is simple but solid.
My thoughts on the modifier implementation
As I've said, it would have been a better game without it. With the difficulty backed off a bit and a winnable boss fight
Other notes
The difficulty was cranked higher than I'd like but really only became a problem once I hit the boss fight as it was usually possible to kill or bypass enemies through degenerate strategies or exploits.
Verdict
I enjoyed this game and I feel it has more potential being fixed up as a good game than as a so bad it's good game.
