Usually use Unreal but been getting into the new XR Interaction stuff in Unity via Valem and Andrew's helpful tutorials :) .

Unity! ;)

I was hoping to try and use Unreal but I've been too busy this past month to refresh myself with it.

Unity for XR Interaction toolkit and Probuilder mostly.

Not sure if I'll have time for the jam, but my weapon of choice? Godot :P

Probably just sticking with unity

UE4 so that I can play around with the ambisonics spatialised audio and the new convolution reverb! :)

I think this time I will try out PlayCanvas. 

Using Unity 2019.3, I think, though I may choose an older version depending on what assets I choose to use.

ill be using godot ! ive been spending the last 3 weeks reading up on it

I’m an odd duck here: using the LOVR framework and writing code in Lua. No assets, no level editors, just pure code (except for audio samples).

Rayne :D (it's my own custom engine)
