This is totally rad! The store page doesn't do it justice. Looks great, sounds great, feels great, I can see myself being glued to this one for a while. My Japanese is pretty terrible, but I was still able to understand the game through clever design alone. That's pretty impressive.
Though it would be nice to have a proper translation with all the UI elements in full English, but not entirely necessary.
Can't wait to see what you'll make next!
