Well there are multiple ways to do this but what you can do is check for a collision with the player. If the collision is true check if the player is above below to the left or right of the object, then move the obj by 1 in the opposite direction until collision = false (I'd also have a counter so if it loops through the code more than a few times it breaks from the loop) you could do a similar thing for the maze walls to keep it from being pushed into them. There is probably a better way to do it though.

Put this little guy in the collision event (exe piece of code) in BOTH objects...

x += 0.1*(x-(other.x))
y += 0.1*(y-(other.y))

small code can do wonders, tweak as needed...

its kinda shaky...

what kind of movement do you use? on a grid? in such case I have to look back on some projects as one of them contains pushing blocks as a puzzle thingy. blocked by other blocks and walls. worked fine. but like said I have to check that out again, it has been quite a while ago lol. (edit:)
got a part example as it contains alot more to make it work propper but this is the movement I used just checking if it was possible to move:
if (keyboard_check(vk_right)) && (place_meeting(x,y, obj_Gnome_play))
&& place_free(x + 32, y) && (!place_meeting(x + 32,y, TestBlock))
&& (!place_meeting(x + 32,y, BlockBorder))
