This fixes a visual glitch in which the "eye" was not displaying correctly in the highest detail level.

Updated graphics for new retina-display iPads. NOTE: There is currently a visual glitch in the highest "detail" setting. We've fixed it and submitted an update to Apple.

Fixed bug in which minus button occasionally breaks.

Some modest performance optimization. You should be able to have a few more bots going at once now. If you notice any bugs, please contact us at vectorpark@gmail.com. Thanks!

This version should fix the glitch which has been affecting some users. If you are still experiencing buggy behavior with Acrobots, please contact us at vectorpark@gmail.com.

We have an update on the way which will hopefully fix the "minus button" problem some users are having. Until then, if you're experience this issue, try deleting and then installing Acrobots. You can also email us at vectorpark@gmail.com. (Believe it or not, we're happy to hear your complaints, as they help us improve our apps.)
