Correct,it is a work in progress yet to be released.Once it is finished,I will put it up on the Marketplace as a merchandise piece.
The thread's goal would be advertisement,I admit, & feedback.Since this is a Smash community,I feel it would attract attention/buyers.I plan for this engine to be easy to use for anyone who knows basic-to-intermediate GameMaker usage.The engine will be Smash-based in mechanics,but if one were willing,they could edit it to be a Street Fighter engine also,or I may update it to include a Street Fighter based engine in addition.
The price for this engine would be around $5.00.
Keep in mind this is not a fighting game,but a fighting game engine.If any characters are included in the product,they would be my own,and would exist primarily for example of the engine's capabilities and workings.
