two locos occupied the same coordinates

[Saumya-Mishra9129]

During press of lowercase keys as well as upperkeys, two locos occupied the same coordinates, so it was difficult to read the letters.
Steps involve - starting game from level 1 , reach to level -4, press lower keys - you may not see error in one try, try from start again in that case. Follow same steps for level-5.
For reference look at pr #14

Thanks. We use issues as a signal that we don't plan to fix something, so I've looked into this issue more deeply.

• as originally written, the random positioning in new_game and _quad_to_xy does risk collision without detection,
• for the initial games this is easy handled by the child,
• for the letter games the solution is not obvious,
• 2ca1280 added a feature to let the child drag to remove overlaps,
• How to use LocoSugar does not mention this feature,
• 1f9c2ac help with overlaps, by hiding the Loco after it is identified by the child.

So it would seem this is adequate, and my review comments in the pull request stem from ignorance of the activity features.
