Online score ,checkpoints and a little question news - Cubic Climber Game

I have a lot of work in these days but I`ve finally managed to learn some basics of MYSQL and PHP , and connect to the database of my "Best times" :D. Time can be uploaded/downloaded ...depending on the situation. Also, if some player improves his best time, it will be automatically updated instead of adding new row to the database. After finishing each level, you can see best 10 climbers and their times (times in table are a bit unreal... I was just testing).

Checkpoints are new addition to the game (It was too difficult :P ) . You can identify them by green color of keys instead of classic black. They are usually on every + - 15th hold. U will always respawn next to your last checkpoint with a little time penalization.(So you probably wont make it to
the top 10)

 

 What was done:
- online score system
- smooth transitions between scenes
- checkpoints
- time counter 

To do:
- better environments
- profiles
- lvl unlock system
- stats ???
- random falling rocks/climbers ???

A little question:
What do you think about registration on first startup of the game? You will only need  nickname and pass(no emails and stupid stuff ). It`s because of protection of your nicknames and stats like : How many times did u fall , What logest distance you were falling ...etc. Of course you wont have to register if you dont want  but u will be without stats and highscores. What do you think about this "stats idea"?
