A voting/matchup game in a jam full of platformers is a genuinely bold and different choice — Twisted By Art was right that it stands out from everything else here. Timpth summed it up well — the music really does make each matchup feel weighty and suspenseful, which is hard to pull off. The bizarre animal matchup concept that dany4240 mentioned is creative and I can see the vision. Adding animations of the animals actually fighting each other would make it so much more satisfying, and the newsflash idea you mentioned in the comments sounds like it would have been brilliant — hopefully something for a post-jam update! Industries Zero's point about Firebase is real, tackling live data in a jam is no small feat.
