Good evening, I stumbled upon your demo by chance, so I had the opportunity to test it.
Extremely frustrating (I'm kidding but it really is). In fact, I wonder if it is possible to obtain a victory. I'm on my 24th attempt, but for tonight I'm going to stop there. xD
In terms of the problems that I noticed, in the current state of the demo, there are several.
It's difficult, very difficult. The slightest "miss" is an almost irrecoverable error at all times. On the character of Mercy, I could see that her failure rate is 10% (because she is a little dumb) but I wonder if in the others it is not worse. Even when they are "tied", I very often manage to miss a simple "caress", while them with the legs tied are still as precise as before.
Speaking of tying, I like how it works, but it's not useful enough at the moment. Using this skill ties up arms and legs, and using "struggle" targets untie very quickly. Too fast to be really efficient. The overall situation in the same round is "I tie you up, he unties his arms and at the next action you will suffer". It makes them lose a turn, but for us too suddenly ... Since even with the feet tied they attack.
In my opinion, the enemies should register their turns of action. This way, if the enemy finds himself attached, he will lose his action, the next turn he will struggle, and again in the next turn he will be able to act. It will be more pleasant for the player.
The option "insult", for the moment I do not see the usefulness of it in the demo. Too little devotion damage (like removing clothing), and only Mercy can use it. Impossible to win with it.
And last but not least, such long skill cooldowns. Whether it is at the level of Mercy's support skills, or at the level of the character "Player". I really think we have to rebalance all that, or find another system, like endurance or defense.
Finally, there it is. Good luck with the development, I will observe the result a little later.
Oh, and sorry for my poor English if I'm not clear on my point.
