Updates of 4 July 2020

Update 4 July 2020:
1)Environment are basically done. I added a map which I created in May.
IMPORTANT: Mac and Linux files are not imported. Will be uploaded at next versions.
Will be added soon:
1)I will add forward and backward keys. If you go forward from your start position you lose points when you get new ones. And if you go backwards you got additional points.
2)I will add old arrows deletion system. For now after each 5 arrows the old ones will be deleted.
