Whenever I see this, and his other games, I'm feel like there should be a simple "Make your own custom game" or something to that nature. Idk, it feel's like this is a cool tech demo of a simple engine that could break open a niche.
However, I got two gripe's, one is that menu-like GUI is unable to trigger whenever I have the time on pause. I don't think I had this same issue with the older versions.
The other is that the game time feel's fast on the slow speed. Characters and ingame actions are fine, but I fell like I'm almost playing speedrun with my mind to make sure I am on time with some things.
