I've just released a post-jam update for my LD49 entry (one of the 3 actual NES/Famicom games on the event)

It's available - both as a NES rom and on a WebGL emulator - here: https://wendelscardua.itch.io/improbability-fighter

Main changes from the LD version: - better performance - new HUD - moving enemies - apples and blocks now deal more damage - cleaner screen transitions
