Thanks! For the sound you can make it play at the right animation frame when the character lands on the floor.
Exactly, the HTML version had some serious performance issues if I recall correctly (probably just Javascript), also the game would almost crash when the plates explode since there is I think at least a 100 objects being tossed around at the same time. Not even preloading objects helped so I gave up on HTML. Thank you again for checking out the game and I wish you the best of luck in other projects!
