Sand-dancer — 3 of 48

Aaron Reed and Alexei Othenin-Girard

Release 7

Section - Undo Prevention

[For the final release, we compromise and only prevent undo just after smoking.]

Include Conditional Undo by Jesse McGrew.

Carry out smoking: prevent undo.

Rule for deciding whether to allow undo: if undo is prevented, say "Yeah, you wish you could unsmoke all the cigs you've inhaled. Life doesn't work like that."
