That was one of the most amazing gameplay moments for me recently, until it crashed. Mysterious, colorful, has attention to detail. The first moments i had with that were full of wonder. "what does this button do" "what happens when i do this" and so forth. I think i wont play more though, cause it wont be a mystery if i explore the corners of that dimension

I'll just leave it at the tingly feeling of wanting to play more.
How long did it take and how many people were involved?
