Going to participate with template that I evolve from Ludum Dare 44 and a few TriJams. Made simple main menu, settings, add polyglot for basic multi-language and build system that can push builds directly to itch.io(my fav part actually).
Still WIP, but feel free to checkout Used assets/tools: part, there are some really cool editor tweaks like CustomToolbar or Editor Spotlight
