T2D Performance Concerns

After dabbling with the T2D demo some more and viewing the T2D demo movie, I've noticed how sluggish the game objects(sprites) are. The more in-game content and scripted sophistication included in your examples, the more this sluggish behavior becomes apparent. Will such issues be addressed in the final release? If not, are there viable work-arounds? I have seen much better , smooher performance in other engines, such as Blitz3D(using the 2D component
of Blitz3D). If the performance can be improved within a reasonable amount of time, I'll seriously condider buying it. :)
