I see.
Just a quick tip: I'd recommend to save CRISTAL up for RTT.1 instead of using it on a relatively easy late RC level like RC.14.
RTT.1 is very hard to beat without losing at least 2+ lives, just because of how long it takes to complete. It is not skippable via

or

since there are no levels with effect items before it, and there is virtually no way you will get to the effect item in the level itself.
I believe at least my first three

, if not more, were obtained in games where I completed CRISTAL in RTT.1.
