susan taxpayer is an upcoming platformer created by mason/punkitt (punkitt-is-here on tumblr), while the music was done by beatrix quinn (beatrix-quinn on tumblr). currently as it stands, susan taxpayer is a demo (created for sage2023) with three-ish levels, a tutorial, office orientation, supermarket scramble, and a breakroom. notably, the game is also made in smbx2, a super mario fan engine. the game is mostly inspired by warioland games (particularly warioland 4), a majority of similarities to pizza tower are coincidential.
smbx2 as an engine is intended for windows, however it can be ran through linux with wine and proton. (this also applies for steam decks, apparently.) i must confess i have no idea if it works on mac or not.
