There are tons of levels that have glitches that you can't jump high enough. Wix Games has fixed it in the mobile version though.
There is also level 1 by mr_ytp, in the third room of levels. On the room "so nice-do it twice", when you kill all the monsters, the fans give the bomb way too much power, it goes right through the ice and explodes on the spikes above. The only way to do it is:
Before you kill the monsters, you have to change gravity just when the bomb reaches the fans so it glitches through the blue monster blocks and explodes next to the ice, resulting in the ice gone by the time you kill all the monsters.
Other than that, this game is a great extension to jumphobia. I can't wait until they release something new!
lol this review is so long
