I temporarily had broken the score submission. It should be fixed now and you should be able to submit your scores without issue. Sorry for the inconvenience.

I made a change today to dot killer that should result in better performance. Previously, the game would loop over all dots and collide them in the Quad Tree and then separately update all of them. Now, the game will do both at the same time cutting out a fairly large loop.

Hopefully this will be noticeable and I hope you have been enjoying dot killer! Keep coming back to Question Mark Games for the most up-to-date builds of all our games.

This game was submitted to Dr. Dobb's Challenge. Please enjoy.

I've also added an enhancement to allow you to lock the firing mechanism. This is a benefit for people using Mac's because of a compatibility issue. Simply press the "L" key while playing and you will continuously fire bullets. You will no longer need to click :-)
