This is truly a beautiful game. The music fits greatly with the graphics. A really good game made with a a time window of only one week. Did you use Blueprints or did you code in Unreal?
I didn't write a single line of code for this game. It's all blueprints.
I was sceptical about unreal and blueprints in the past but I am SO glad I tried it. It is the perfect thing for prototyping stuff which again is a perfect fit for game jams.
Ok thank you. I'm getting into game development now and I don't really knew what to use so I made the game with unity. But now I will most definitely try out Unreal with blueprints.
I would suggest you spend as much time in unity as you need to feel comfortable with c#. once you got that blueprints should be absolutely no problem for you.
Without my experience in Unity I think I would not have enjoyed Unreal at all.
