-1 I personally love the player collision cause it spices up the gameplay and adds some level of randomness. Also, if you get good with it you can use it to your advantage. Please keep it, it makes the game more fun!

Also provides an element of strategy where you can have the upper hand against someone who is just as good as movement as you. Traditionally, TNTRun is just movement but collision does add an extra level of quick-thinking, bravery, and strategizing.
