warmerise without sprint will increase the gap between pro and noob! not just for the difference in arms, preventing escape to those who are disadvantaged! but especially between those who have gravitygun and who does not! favoring those who are already ahead I do not find it right, there is no reason for this. so there will be no more competition. the noobs will ask the pro weapons and gravitygun, which happens already. they will abandon the gameplay. it will be the decline for warmerise. all games of this kind have the sprint, now warmerise no .... and this is a step backwards, a level rise!

THE PROBLEM IS WORST!!! GAMEPLAY NOW IS VERY IRRITATING!!! WARMERISE IS A GREAT GAME REALLY.... BUT SO IS UNPLAYABLE!!! MAYABE WEBGL IS THE FUTURE.... BUT NOT FOR NOW!!! (EXCUSE FOR CONTINUES POST, I DO NOT WANT TO GIVE ANASTY.... GOOD LUCK GUYS)

Looks like you are rendering without using requestAnimationFrame for the main loop. You should use 0 for the frame rate in emscripten_set_main_loop in order to use requestAnimationFrame, as that can greatly improve your frame rates! (another message from chrome's console)

no change, new and old maps.

   maybe this helps
