I understand what you're saying, it just initially sounded like feedback was unimportant because it was designed to be frustrating (which you must admit is a bad design position to start off with.) I'll try the game again today keeping in mind you went for weird positions (such as impaled in the wall) and see if I have better luck now that I understand how the matches work as well.
The mouse issue may be a mixture of hardware and game balance or something else entirely. If the dont move segments are supposed to be the hardest thing in the game by a mile, then it works, but on my setup it is particulalry dreadful. I can't think of anything else in the game that is anywhere near as frustrating, but from memory that was the only real minigame. Defending in the other sections is a simple drag and drop weapon movement. Anyway, I'm running win10 64 bit, sensitivity set to just under half, razer deathadder elite. Any info that might help beyond that let me know.
No, I didn't design this game to torture players (too much)... but this is a game that will not hold your hand as you go through it (or when you start). I am sorry if you're against the design choice, but for this game (type and length) it makes sense. However, I feel like in this case it's a problem of the [don't move] section on your end since you're unable to beat it even once (as far as I understood). I spent the entire yesterday thinking about how to improve the [don't move] without making it drastically easy. I could make it so that the game keeps track of how much you're losing at the [don't move] section, and every time you lose it will get 5% easier (at least on EASY). However, if you reach a certain percentage of help, the game will punish you in a way (just in case people take advantage of the help they are getting).
I'm glad you got the hang of defending yourself in-game (some people didn't know how to use defensive items at first couple playthroughs). I checked my mouse settings: pointer speed is set to middle and [Enhance pointer precision] is toggled on. In case it helps, the "dot" in [don't move] section needs to be kept in the middle for maximum survival chances. If you drag it near the edge, there's a chance it could jump to that nearest edge. Good luck and let me know if you made it through, I have my fingers crossed. :)
