Coalescence is a game in which the player must connect to blocks so as to make themselves bigger or into specific shapes that fit into difficult-to-get-to areas. Right now it’s only one level but I hope to make a full version with many levels, a better ending, and many more features at some point. Anyone who donates to the game now will get a free version of the complete game whenever it comes out (which may be very soon, a long time from now, or never; I really don’t know).
