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 concept of the puzzles with two player characters pushing stuff around overall.
What I didn't like
The lack of sound.
Did I think it was so bad it was good?
Not so much. It really came across as an earnest beginner's attempt at building a game, with some innovative gameplay, than a so bad it's good game.
My thoughts on the modifier implementation
Assuming it's unimplemented as no note has been made and no implementation is obvious.
Verdict
It's a good attempt and a neat little game, but not really so bad it's good in my opinion.
If you have any questions, comments, queries or concerns, please reply and I'll do my best to get back to you.
