Thanks for the feedback, I didn't had something in mind till the last moment and the tils being smalls didn't helped at all. I would probably update and add wasd instead.
The fog is just a layer on top of the maze, so you can still use explosives.I don't intend to change it,making a strat around it sounds cool to me.
Well after designing the first maze, I realized how easy is to visualize lines in your mind to solve the mazes. There is where 2d mazes faill, not having an extra axes to hide the dead ends and the whole identity of the map. So the only way to make the maze more harder is to increash the size which is questionable if it's enjoyable for the player. I solve the issue by adding fog, much harder for the brain to map the whole maze and there is a trial and error aspect that makes it intersting.
Hope you had a fun time.
