So, since you asked for it, here's some feedback:
1. Don't lock the mouse unless you have a really good reason to (like using a first person camera). It's obnoxious, especially without an easy way to unlock the mouse (like going into a menu on pressing a button)
2. It's a good idea to have a target resolution even if you're planning a resizeable window and for the target to be something that already feels nice. Not all players will think to resize the window due to how many games don't give that option. 1000x1000 is a really awkward window size.
3. Regarding the contents of the readme file, it is actually pretty rare for players to mess with the contents of the game directory. You can generally assume the executable and the game resources will be in the correct spots within the game folder as long as you put them there. Telling players what they're supposed to be doing in-game is more important. The same goes for this page.
4. In this type of game, the starting position for the camera should give a good view of the player's stuff. That makes it much easier for players to make sense of what they're looking at.
