Debug and fix not working examples from C#

Avoid obstacles test.

• Timeout for when reaching Game Over page & test is freezing #4

Notes:

• the current PR is a workaround for fixing the problem with the freezing TestAvoidingObstacles (caused by the obstacles that are not seen properly)
• currently the test will sometimes fail because of the bug in the TrashCat app
• the report will be generated because the test is either failing or passing in the end.
