also when I see some people's posts (not meaning you here Lucas) and the variation of their topics I wonder if some are building an apps that replaces all existing app and games into one single app
no wonder that you (not you Lucas) can't finish something when your scope is so wide and jump everyday on a totally diffent app type.
Coding takes time and copy pasting doesn't teach you much so it's normal to get stuck at some point.
Put it aside for a few weeks and start again with a fresh look at it and that might help sometimes.
A fail can always be corrected to something functional, Lucas. Jump in on the chat and we try to help you there aswell.
