Version 4, combat update

I'm back yet again with another (semi) major update to my small little project that's stared consuming my life.

Today I have come to share news of the combat update, no longer must you pick up laser charges to shoot as you now can collect power from damaging the boss to upgrade shot speed and damage.

I've also added a few things:
- added hit indicators for when shots connect in the form of sprite
- reworked combat
- reworked boss difficulty to match new combat

Although this was a more or less small update it is definitely one of the more important ones for this games future.
thanks for playing and good luck!
