Here's a build. This might not be the last, because I might try to get an extra level in.
Posting it as a .zip is OK, right? If not, please let me know (with haste, since there are only two hours left, ha).
Unfortunately, there's only a short tutorial level and another level, so there isn't a whole lot of content just yet.
The controls are explained a bit in the tutorial, but it's not necessarily as extensive as I'd like it to be, so here they are again:
Control Scheme 1:
WASD to move and aim, J to jump, K to fire, L to fire soul blast, Space to dash
Control Scheme 2:
Arrow keys to move and aim, Z to jump, X to fire, C to fire soul blast, Space to dash
Press R to restart the level; if the unspeakable happens and you end up falling off the map (it shouldn't happen), this should get you out of it.
The goal is to slay all of the 'demons' in each scene, and to use the souls of humans to help. Three souls can be paid for a soul blast, which hits up to 6 entities (humans and demons alike), and deals double the damage of a normal shot.
Alternatively, it might be wiser to save your souls up; every 2 seconds, you heal 1% of your health for each soul you have.
Your souls are visible under the health bar in the top-left corner of the screen.
Souls on the ground will turn red over time, and once they're fully red, they'll turn into demons; if you aren't careful, you'll have a horde of demons on your hands.
