I love a game that lets you cram a bunch of favourite characters into one big self-indulgent crossover and games that are about Defeating the Narrative, so I think I'm very much the target audience for this. I'd really like to play this game with friends and lean into the joy of tormenting favourite characters until they break reality about it!
It's appealing and feels fitting for a Havoc Engine game that this game's approach is to immediately 'vastly oversimplify [your] Characters', and I like the guidance for making those simplification choices. The visual design also made me laugh in delight.
I can see the plot of the Alternate Universe dissolving and crumpling in on itself in weird ways as the game progresses and characters get closer to their canon selves - I feel like this could be extremely cool, but could also feel disjointed and strangely paced. I'll echo other comments and say that in an ideal world it could be helpful to have some further advice or guidance for helping the game hang together as the story splits apart - for example, more clearly marking the key Plot Points that you might plot your session around in the examples list.
Thank you for sharing your game with the jam!- Jim
