The "pull to hand" upgrade is a leftover that I wasn't able to "clean up" in time. The Recovery status (hold Q) was initially an upgrade that had to be purchased in the shop, then it was moved to the default mechanic... so "pull to hand" is nothing more than the ability you already have at the start, it simply remained within the shop's pulls because this change was made 2 days before the end of the game jam! I apologize if this causes confusion f(^_^)
