Fixing it would either involve making the other person invincible as soon as they get hit, or making the hitstun from Lenny longer. I won't be doing the latter, and I'm not sure how hard it is to do the former. I sorta see this as the player's problem, though.
That'd be cool if you could fix it, but I didn't really have my hopes up about a fix to something just being a better player could solve. Thanks for the response!
