Elliot Quest developers already sent in patch to deal with slowdowns on 3DS
The PlayEveryWare Twitter has responded to a few people regarding slowdowns with the 3DS version of Elliot Quest. They have identified the problem as a memory leak that got past their QA tests and have already submitted a patch to Nintendo. They also offer a work around until the patch is live by stating players should restart the app every so often.
for 3DS? we found the cause and have a patch we're submitting to Nintendo tonight!

Yeah sorry about that!! There was a memory leak that got past our QA test. The best workaround for now is to restart the app every so often
