I am also in!
It't been 10 years since I completed my first and only LD entry, and about 4 years since I really touched anything game-dev related... but I think this is a good opportunity for me to re-learn how to have fun developing something playable.
I will be using Blender, Unity, photoshop and FL Studio - I might also use some Substance tools if I have the time / need.
I will probably stream a bit on twitch... but it will probably just devolve into a shader graph tutorial watch along stream!
Looking forward to seeing what everyone does with the theme :)
However I did get a decent amount of gameplay / card design done and a lot of it should be fairly straightforward to implement (touch wood).
