It’s great to see how far your game has already come, you’ve definitely improved the combat by a lot since the last devlog, it has much more impact in every hit and seems much more polished as well.
Your problem with the execute mechanic reminds me of the 1. Shadow of Mordor (Lord of the Ring) game, because they had a similar combat though without heavy and light and only one attack, but for that they had blocking.But anyway, what I wanna say is in that game you could execute an enemy that was thrown to the ground, however it took quite long and other enemy’s could disrupt you while it which balanced it out, and the game also had a combo meter, and with every attack it goes up by 1, but when your hit it would go to 0 again. When you reached a combo meter of 8, you could instantly execute 1 Enemy nearby without being disrupted. This worked however, because you cough against many enemies at a time most often, but that game was also a heavy stealth based and combat one, so your game just kinda reminded me of that.
So what I wanted to say basically is that your game is absolutely fantastic, and that they are multiple ways for the execute to work without putting a cool down in it. My apologies for all this text.
