how can I get access to workshop maps and creat my own maps?

Just downloaded the game on Windows 10 machine using Steam. But all I get it the yellow splash screen. Using mouse doesn't start it, Using a game pad doesn't start it. Pressing AWSD keys gives sounds, but nothing else changes. What's wrong?

A fun little game with some "issue"... - There needs to be some info about how many puzzles are still left - When I click "New Game" accidentally, will there be a warning or will it just delete the actual save and start fresh? Besides that, performance was great, the art style is nice, replaying levels with different bombs is also fun....

Just completed the demo! Looking forward to the game! Hope workshop + editor will be added later on for endless fun <3

Playing pre-release from LurkIt. I have feedback for the developer. How can I contact?
