Should I make a demo of this consisting of one game? The full version is planned to have 4 games, with updates adding more games.

yes, release the demo, but don't release your plans until you have received a lot of positive feedback on your demo. (if you don't get good ratings on your demo, make it better)

Gotcha, thanks for the advice!

Is this something you would need help with? because i could help if you need help. :)

Only if I'm having trouble, I'll ask for your help. Thanks! :)

make a game with me in it!!!!

srry for spam. it's sorta rude
