I tried to fix as many things as I could, but it probably won't be everything that was requested, but it's quite important things.
- The first thing is finally checkpoints, checkpoints are added in certain places, so it won't be necessary to continue from the beginning in some maps.
- A larger damage range has been added and the angle at which damage is taken should make it easier to hit a headcrab or a manhacks.
- Manhacks now only have 30 hp instead of 50, they should be killed in three hits with a crowbar or weapon
- Ambient were adjusted so that they didn't have any distorted parts and looped without any strange sounds
