Good point on the multiplier affecting simplicity. Reminded me that much as possible I'd like to keep things simple--like anyone even a grandma can play it, and everything can be picked up fairly quickly without needing much explanation.
Regarding the auto-block, that could work in the way of simplicity as it might open up a button for level change, but it might promote turtling? Also, I don't know, I never got the hang of blocking without inputs, this was always my downfall with tekken. Never felt natural, maybe got used to SF.
A hit forcing the player to stand is an interesting concept. I'll see if I get anywhere with it. I'll continue to brainstorm and do some tests. Thank you so much for the feedback, these are very valuable to me.
Maybe I was slightly misunderstood, but I very much DON'T want the block input removed. My thought was that ducking is already an inherently defensive "move", so blocking while ducking would be redundant, but while standing it takes more effort. This is how it is in real boxing too, if you're standing upright, you must choose between defending your head or your midsection on the fly, but not while ducking and weaving since your center of gravity is low, and body is curled up and easily defensible, so long as you don't go on the offensive. Turtling isn't a problem as long as there's a way to defeat it.
Part of why I love this game so much is because even in its simplicity it feels more real than many high budget boxing games. There's no jank, no flashy fantasy effects, no tacky game mechanics, just a visceral and realistic 2D boxing match with a boxer that looks and moves like a boxer.
Ah yes, I re-read your comment and I realize I misunderstood. You meant auto parry body shots, I mistakenly thought for all. I will do some tests, try out your suggestions and also those by others, see what works well. Thank you for the feedback.
Also, thank you for the praise, I'm not sure I deserve it, but I am glad you loved my game so I'll take that win.
