I really enjoy getting the projectile and 100% is the most logical next category i suppose... if not "goodending". But, watering cans only doesnt let use shoot stuff. Although, it is the other intended ending in the shortest time. For 100%, 1up collectibles are 1 and done, but all other pick-ups (barrier and invincibility) reappear after deaths or leaving the areaa. Would we pick up everything once and just leave it if it reappears, or would we skip the non-permanent items?

Calls into question what to do with the radio as well, because it only lasts for the screen and can be hit again if you leave and come back. For consistency, if the barrier and invincibility are excluded, the radio would have to be as well if we exclude on the grounds of the items not being permanently consumable.

Though I think the run would be more interesting with the radio, specifically the second to last level where you would have to drop down and traverse a particularly dangerous set of spikes.
