I'm trying to figure out what the expected action is in this scenario. Let's assume that there is currently no shift delay and we're at 20G. If we've got this position and the shift right command has been entered: Code: I XXX IIIXXX XXX XXX XX XXX XXX XXX XX XXXXXXXX Do we expect it to catch into the top notch or slide after it's at the bottom? This is assuming that the shift command was entered either during the spawn delay or the first frame of the fall, before the block has fallen any. Certainly any shift entered a frame later would be processed at the bottom of the fall. It seems to me that it should definitely be able to slide into the top notch if the user is able to press the keys fast enough. This question is actually a result of a completely different case, so if this seems unimportant in and of itself, try to answer anyway. Let me know what you think. Thanks again.
