This will be my second LD Compo I will be part of, pretty excited, my last game turned out alright, it was fun, but lacked in the art department and there were quite a few things that could have been done better. Anyway here are the tools I plan to use:

Game Engine:
Depends on theme and game idea but between
Unity
Game Maker Studio ( <  Probably this one because it’s super fast to get something working )

Art Tools:
Photoshop
Google

Music and Sound FX Tools:
BFXR / SFXR
Stock Music
Google

Good luck all and have fun!
