That bug with the inputs not transferring bothered me so much while testing! I have no idea what causes it, based on my testing I think it's a Unity bug but I didn't have time to look into it deeper. It doesn't seem to occur in the web version which is probably why you're the first one to report it.
Enemy balance definitely needed a bit more work, lots of people have complained about that. I was going to reduce the health of those red crows but it slipped my mind before submitting... Knockback is based on the enemy's relative position to the player which is definitely not the most intuitive way of implementing it. I'll probably try to base it off the actual attack direction in the future.
I don't have any active plans for SMVM unfortunately, but I'm glad you liked whats here!
