First
One route, no loops
The maze is carved by a backtracker and never joined back up, so between any two cells there is exactly one path. That is what makes a wrong turn wrong: it cannot come out somewhere useful.
A maze in three dimensions, drawn fresh every time at whatever size you set it to. Exactly one route runs from the corner you start in to the one you're aiming at, and every other turn is a blind alley that was made longer on purpose.
Arrow keys on a keyboard, a swipe on a phone, or an on-screen joystick if you'd rather. A key press moves you one cell; a swipe runs you on until something stops you.
You start in the top-left cell and the exit is in the bottom-right one. Twenty-one cells are on screen at a time, whatever size the maze is; the rest of it is the minimap's problem.
There are no loops, so a branch off the route is always a dead end and never a shortcut. You will not know which is which until you have walked to the end of it.
Coins are lying around the maze and count towards a running total. Bombs are rarer, and they are the only thing in the game that will get you through a wall.

Then
Once it's carved, the generator goes back over the dead ends and extends them, spurs new ones off the junctions, and then lengthens what's left a second time. None of that is decoration.
Amazein runs in a browser tab, free, and asks you for nothing at all.
No account, no advertising, nothing to buy. Your settings, your best times and your coin total sit in the browser you played in and go no further. Reach the exit and it draws you another one, which will be different and no more helpful.
