I have finally finished my side project hardcore puzzle game called Trappped which combines some elemens from Trainyard and Spacechem. Your task is to move blocks to their designated positions. You do this by creating instructions: - move - combine - split
Very interesting. Aside from what the author had said about the game's inspiration, it also reminds me of some elements of the infamous Chu Chu Rocket (yep, old school). The synergistic ability to merge different "blocks" into one and then move it en bloc as a whole is particularly intriguing. Will try it out when it comes out.
