Fun game! The whole time I was wondering when the theme would kick in until the ending moment. Very clever. A relate to this goblin very much.
The puzzles weren't challenging and were a little time consuming, but I don't think this is trying to be a super in-depth and intriguing sokubon. It's just dumb fun as a goblin.
The minigames where you're collecting the relics were a highlight of the game. It's impressive how each one was unique. The lacking point was definitely the sokubon gameplay. Though you did a lot to polish it, it needed some more interesting level design and mechanical hooks. If you acknowledged the sokubon was building towards the relic segments, I think you could've found a design solution for the sokubon gameplay to be repeatable (easy to impliment) and act as a baseline of entertainment in the game.
Good work. I hope goblin got to hang at the function.
