Back to Light was a one-week-game-jam project, where you play as the Vampire Zachariaz who tries to cure himself of his Vamprisim - he wants to get back to light.
The Game is a 2D Action Sidescroller. You have a few abilities, some of them need to be unlocked through books you find on the maps. Finding leavers to open doors, fighting Priests and Vampire Hunters to reach your goal: the blue potion that makes you human again.
You can try the webGL build here: http://gdw-ss-18.pages.fsi.rocks/back-to-light/
all the core mechanics can be found in there, but there are just a few generic levels, nothing with a story.
also a few features (e.g. AI) need tweaking but its absolutely playable.
