Adjustable user interface
The core loop in the game is adjusting the analog clock. This can be a challenge if it is too small and the user has a small phone. A too big clock will also block too much of the game area. The best solution is to start with a good average clock size of about 25% of the screen, but then let the user adjust that if wanted.
Smoke trail after moving units
To help the user notice which units are moving we have not added a small smoke/dust effect. A very small change, but it has a huge impact on the experience.
