Thanks for the comment, I agree about the controls, but didn't do it on the numpad because not everyone can have numpad keyboards. I think to add settings and there the ability to change controls, but for this I will have to rewrite the code. About character getting stuck. BoxCollider2d hangs on it. But the generation of the earth occurs randomly every time and there are 2 types of earth in total. Players can get stuck due to the fact that the positions of these 2 types themselves are different (one is slightly higher, the other is lower). Unfortunately, I noticed this when there was no time to fix it. Shooting and digging faster is very easy to do. So wait for the update.
