How to unlock hidden achievements and in which mode should I play – I, II, *, or creative?

Hello, is there a way to save the map/progress? Thanks.

Let me start with what I like in this game. The simple connection rules for tile placing are relaxing and simple to follow, giving users a pleasant experience. The art style has a unique charm. Hexurb is a very good addition to its game genre. Some changes to the game will make it more appealing to the users. 1. Disable clouds: Clouds cover half the map at any given time. For landscape building games like this, visual clarity should be a priority than environmental features (cloud, fog, wind). See how...

Is there any way to run the game in a window? I'm physically disabled, and need to be able to use my onscreen keyboard, which doesn't mix well with fullscreen. I really hope so, as I could use more chill games.

... but the game would be greatly improved if we could save, and come back later.
