Version 0.3.0: Pixel Art!

In this update:

1. 31 new levels in pixel art style! They depict various technologies, nature and buildings, and do not contain unnecessary complexity, allowing the player to relax a little and enjoy creativity.

2. Adaptive design, like on the web. The interface now adapts to each screen resolution, providing the most pleasant experience while interacting with it.

3. A lot of refactoring has been done (improving the game code). Several bugs have also been fixed (not critical, but still).

4. Although this is not yet available to players, the solver and generator for the level editor have finally been implemented! They allow us to significantly speed up the creation of new, not too large levels.

Unfortunately, the more lines at a level that can be drawn simultaneously, the slower it is solved automatically. Alas, this is not due to poor optimization (although there is still room for improvement), but to the “nature” of the game. [expand type="details"]So, according to my rough and optimistic calculations, it is theoretically possible to create a level with hexagonal tiles, consisting of only 2 sources and 3 operators, in which the number of combinations is so huge that it would take more than 366 years to be solved on any modern computer. However, this is not a topic for a patch note.[/expand]
