Thank you!!!
Yes, I do love 3D. I'm actually a 3D Artist and I decided to make this project to keep learning programming. I spent my time hitting my head against walls in order to put all the interactivity together and I ran out of time for the art. I'll keep developing it. as you said, it's a template I can work upon :-)
Go for it, take a look at Unreal. It's so stable and Epic Games has already made so much work ahead. Blueprints are awesome.
Yes, there's something supposed to happen when you touch the small cube but it's not integrated yet - The entire environment unpacks and it's supposed to have an entire landscape popping out as the reward for accomplishing the level. I'll try to integrate it in the next weeks.
