I just watched these out of curiosity, but I can’t help but comment on the videos you posted up.
First off, I totally commend you guys on trying to think outside the box with this game. No jumps, everything is blockable (no true combos), three levels of blocking, and the “preview” system are all very unique, and I think that’s great. I would argue NOT to change any of these systems to be more conventional. Instead, figure out ways to keep these systems and still make it playable.
That brings me to my second point: I honestly believe that games will last forever. Being a community that has seen stupidly fast-paced fighting games at their highest level, I honestly believe that thanks to the preview system, 99% of the moves will be blocked in a high level match, especially with players who have ridiculous reaction times. Sorry if you have no idea who these people are, but I’ve seen Sanford Kelly block ridiculous mix-ups by Justin Wong in Marvel Vs. Capcom 2 that no human should ever be able to successfully block. Literally 5 or 6 different attacks of high and low within a sequence of 1-2 seconds.
What I think you can do to combat this is to utilize the stars a bit more. Make it so that the more stars you have, the later the preview flash shows up. So at 0 stars, the preview flash comes out at the time you have it now. At 5 stars, the preview flash comes out just barely before you attack. When you ge to 6 stars (which isn’t there by default), your preview simply goes away.
That allows you to make the Supers a bit more powerful (so that maybe they CAN be comboed if one isn’t blocked) because you lose more that just the meter losing those stars. Also, I would consider making certain moves drain your opponent’s stars (like the Headbutt). Maybe even landing hits in your Super drains the opponent’s Stars as well (like one star per each time you successfully connect a move in the Super). What that does is make it more tempting to USE the Supers… because even though you lose your Stars, if you land enough hits, you’ll make them lose their Statrs as well, promtping people to WANT to be the first person to use the Super, as opposed to sitting on it for the benefit of the shorter previews.
Also, as it looks right now, the cowboy looks WAY better than the martial artist. I would suggest giving the martial artist moves that start the same but hit at different heights for more mixups. Maybe give the martial artist some moves that lack previews like the Headbutt. And the lasso move seems overpowered, especially 'cause there is no jump. Anytime the opponent misses a move, you pretty much get a free lasso. Granted, there is no true combo after that, so it’s not horrible, but it’s definitely a move that sets up a lot that will be very useful.
Just my two cents for now.
