I don't know if anybody else done this yet.

How to get multiple Mercuryblasts: After you get the two Mercuryblasts for Flinn and Lauren, Penelope will keep on repeating "How are the Mercurys?" if you try to interact with her again, preventing you from getting any more Mercuryblasts. However, if you leave The Night Market area and go back into The Deeps area, then go back to The Night Market area again, the dialogue between Val and Penelope will be reset, enabling you to ask for two more Mercuryblasts again, which will add up to the ones you already have. Keep on repeating this to get more :)

Hey adrian/sevencrane, please don't remove this dialogue resetting thing :D

Amazing game by the way. The Music and art style is awesome. I like how cozy the Deep Town feels. Definitely one of the best ones I have played so far (but I don't play many games).

100 Mercuryblasts

Hahaha, this is awesome. Nice catch.

Ok so I'm not going to remove the stacking, but I will make Penelope cut you off after eight Mercuryblasts because it's her job. I think it'd be a funny easter egg for people to find without having to reload a ton of times.
