Really like the concept, but the character going left glitch stopped me from trying enough to get past the harder segments
On thing, maybe make it clearer how long slomo lasts? when the screen size changes the world slows down for a bit, but then it's very hard to keep up with mario when time speeds up again (and you aren't prepared for it when it happens) or if there is some system to make that clear maybe make it clearer? and also some ways to manipulate the camera speed for the faster segments would be appreciated
Still very good job, and I'm kinda sad that the glitch stopped me from playing it further
