"99Things" -- 2025 CGA (QB45) game

Hello Rugxulo,

Nice game.

Minor gripe: it seems to me the game executable was compressed twice, first with exepack (or similar), then with UPX. It might be possible to improve the compressed program size if one can skip the exepack step...

Thank you!

LZEXE has a tool called upackexe: https://pushbx.org/ecm/download/lzexe.zip

There are several more referenced by https://www.bamsoftware.com/software/exepack/
