Thanks again! Here's a look at the WIP mobile UI, which as you can see compared to the Alpha 6 version, has received some changes, which should make it easier to press certain buttons while playing on a mobile device. Also, certain parts of the UI (like the stamimeter) are planned to be scalable as well, which is another improvement coming to Beta 1.
And I can now confirm as well that the version number of Beta 1 will be V0.3.0, since Alpha 6 was V0.2.5b, so increasing it from V0.2.5b -> V0.3.0 makes sense.
Also, please note that the level shown in the development screenshots was just to test out the custom textures feature and object scaling, which both work great, and that it likely won't be included as a level (even as a secret or test level that can be discovered) in the final Beta 1 version.
