Morningstar Descent to Deadrock
Point and Click Adventure
Windowed or fullscreen.
All texts are spoken and fairly good to read.
Mouse only. Only single clicks with LMB required.
The game has a nice (rather short) story and you never have to be quick. The puzzles are rather easy and you don't have to look for pixel-tiny objects. All relevant objects will be highlighted if roughly touched with the mouse arrow.
I solved it in four hours.
