"I tried to make collisions, but I didn't manage to do it and I spent the whole day doing this task unsuccessfully."
That is the resume of yesterday, but it was sad leaving all like that, so I waited a day more before writing something.

What did I do today (and yesterday)?

I made collisions on the map and also very rudimental jumps and gravity, but the controls are not very good now, so I'll improve them the next day.
