The timepiece doesn't appear... It's a known issue as stated in the mod description. But! What do those art pieces show? I have to know! Other than that, great mod thank you! i had a lot of fun. (the time piece issue pretty disappointing though)

also here's a guide.

tier 1:Art 1: next to vanessa and snatcher

tier 2: Token 1: be yellow and jump on edge of wood platform and big yellow box (in the first 'room' of that tier)
Art 2: underneath wood platform in third 'room', where you first learn how to ride a coloured line

tier 3: token 2: the first time you ride a pink line, just ride it back and you'll be flung at it.
art 3: in the town center, it is above an arch.
art 4: behind town , use ice hat to get it at bottom of lake
token 3: in town, climb yellow box to the pink line with a red sphere. use brewing hat to shrink red. ride pink line (you're blue now.), jump back, ride pink line again (you're yellow now) . then jump along the tree leaves to a yellow totem in a tree house.
token 4: in town, there is a little tiny building with the token visible, but blocked by blue barrier. follow the blue dotted line to see where you need to go.



tier 4: art 5: jump onto roof of building, then to some wood platforms on side of tree, then along the leaves to another tree, onto a branch of that tree, and some more leaves.
token 5: cross the bridge as yellow, ride the yellow line, bounce on spring, ride yellow line. once you regain control, jump to ground below tree. behind island is wood platforms with token.
token 6: at the top of the blue section, there is a red wall. throw brewing hat potions down at the blue lantern until you hit it. Personally, i was able to do it standing inside the red wall. now that you know where to stand, do it again, but move out of red wall before the potion lands. now you're blue and you can jump on balloon to token.

tier 5: token 7: once you get the first blue, bring it back to behind the wall of the 'room' you started in. there is a blue totem that gives you the token.
art 6: on the roof above vanessa's shadow, jump to the short wood pillar, then to the wood pillar nearest it, then to the other roof with the art on it.

tier 6: token 8: follow blue ramp to the roof above the starting 'room'. jump to wood pillar and then to the roof above snatcher. then jump along four more wood pillars to a final roof with token
art 7: find section with a bomb, yellow lantern, blue lantern, and a yellow bridge that turns blue halfway through it. cross it, then jump up the wooden pillars to its rooftop

tier 7: art 8: in shed left of the first blue lantern
art 9: on top of the two big statues in the center of town
token 9: go to the mansion, and you can see a yellow dotted line that leads to the right, where there are some wood platforms. jump to the end of those. there is a yellow totem in a treehouse but there is a red wall in between you. start brewing hat, jump across, throw potion in midair at yellow lantern below. Hopefully your potion lands after you have gotten past the red wall and are safely on treehouse. If you are not yellow though, just jump back across and try again. if you are yellow, activate the totem, and then follow the porch to the right of the mansion's front door to the final token.
