Spherun:

In Brief:
Spherun is a simple 11 level, top down physics based puzzle game where you have to navigate the ball to the yellow exit point by avoiding or smashing through any obstacles using the arrow keys.
Care needs to be taken not to knock down the walls otherwise you may block your way to the exit and do not leave the blue platform/background otherwise you'll fail.

Press Esc to return to the main menu. Clicking on play will bring up the level map. All levels are unlocked from the outset.

Levels become steadily harder to beat as you progress through the levels. Watch out for the balls momentum, The faster you move, the longer it will take to stop moving.

Conclusion:
Overall Spherun is a decent physics based puzzler and ideal for coffee/tea break situations where you need to take a short break from more important matters. My only negative would be the number of levels included with the game. It's more akin to a demo than a full version game.

Notes on Security
I scanned a zipped copy of the installed game using Virus Total and it found zero hits from ? antimalware engines. You can see the scan HERE.
