Hey there. I have a few thoughts on this.
- I enjoy the atmosphere, the music, and the gameplay, but it's very hard to understand the environment.
- I can't tell whether there is any incentive to let go of left click. If there isn't, it might as well be held down the entire time, and if that's the case, that's mostly uncomfortable.
- The game is already compatible with hundreds of controllers, because you can use profilers (like JoyToKey) and plug the keyboard/mouse defaults into them. If you do include formal controller support, I hope it's specific to Xbox or PlayStation controllers, rather than a generic imposition.
- The opening and title sequences are too long, and they make getting a "game over" too unpleasant.
