The current state of the game is quite early, and much is being rewritten.
b22 was as polished as I could make it as it would be the final version of that type and it's format had been well established, but it had many periods where it was much less functional.
This is simply the nature of things until more of the rewrite is complete. At the moment it is only in it's most basic form.
Also, the change in UI and graphics is to prevent issues on certain devices who don't report resolution properly. This made the game unplayable on certain android devices. If it is too small, use the UI scale slider in settings to improve this.
You can expect similar polish to b22 in due time, and also expect similar simple projects to Our Apartment preview eventually.
