Alpha 3 changes

This is the first devlog for SSD! I might change the name later...

Anyways, this is the most major update so far. Here's a list of changes and additions:

1. Score system implemented. The more enemies you kill in a row the more points you get.

2. An actual death thing.

3. Longer cooldowns for spells.

4. New flash spell added. (the other two minor spells don't have code yet)

5. New ghost animation and code.

6. Tweaked the blitz code to be less stupid.
