This is overambitious project that was rushed to meet the deadline for Procjam 2017. Hopefully I will find the time and will to develop all the planned features that were cut out for this submission.
Enter Cave Alive! You're stuck inside the cave with no way out and the walls are closing in! Find the Cave's heart and put it down for good!
WASD - Move Camera*
Left Mouse Button - Set walls to dig
* Fog of war is a feature that's planned for! Try not to abuse the camera too much to find the heart for now...
