The bouncing was to add to the rise part of the theme; however, there is a hidden mechanic I added to make it less annoying - you can bonk your head on an object above you to negate the bounce and maintain some of your momentum. Yeah, I sadly didn't have time to implement the upper floors destroying themselves as you progress so it can get pretty laggy, but it does take a while for it to start lagging badly. Thanks for your feedback! :)
