Effort put into competitions on this forum

[Evil Yoshi Toes]

It would depend on how all-out you go. If you make a really ambitious drawing or sprite, it could take more time than making a very simple minigame. But then that also depends on skill level. If you're good at art but bad at coding, it'll take longer to make a game since you'd have to learn a lot along the way.

I barely submit to competitions so I couldn't really say how long I personally would devote to each of these. Hopefully over this summer I can submit to more competitions.
