It took me a little while to figure out what the objective was, but once I figured it out I enjoyed the game.
A quick tutorial at the start (even just a text description) would help out a lot.
It also took me longer than I care to admit to figure out what "quack" is code word for

This game is really fun. I do wish you could strafe, though. It's probably the most creative game in the jam, even if that may have been at a detriment to the theme implementation.

I like both audio and graphics, reminds me of early 3d games. Controls as well ;) I had to play 2-3 times before properly understanding all the rules (I think?), but still had fun :) Idea looks like it has potential (so it is... charged?;) pun intended).

I really like the audio ^^
Did I hear the duck quack?
