Hey,
Thank you for your feedback and I have some answers for you right away.
Super Dungeon Maker is not a software where you can export a game. It is a game itself and this leads me to the second feedback if we allow your own sprites we have to check them all beforehand if we could approve them otherwise we could get into a lot of trouble with the different platforms and a lot of stuff/movement can start to feel off and won´t fit 100% which also might break the fun for some players.
Cheers,
Flo from rokaplay 💚
