Well, it s my first game jam too! Good luck!

You could switch to GameMaker 2, the latest version GameMaker. It s very good.

Yo, you can make your game better in many ways. You can add transitions, add sounds, add effects, and also improve the game itself in other ways like adding easter eggs, a menu etc. Making a game jam game in just 1 day is not quite a good idea, as there are people that are gonna work to the game till the last second of the game jam in order to make it good, polished, fun to play and original.

GameMaker 2

Yeah, you can technically use any game engine. The most important thing is the game itself, not what game engine it is made in. Hope that helped!
