I don't feel that is useful for tower to have normal dolls at floor 150, i really would feel the rewards should be more unique like relic dolls or epic dolls
Also cash increase the more floors we go instead of 20000,or something more useful
#Make tower rewards epic and relic dolls

As someone who has lately been interested in the tower I do agree with this it seems like a cool concept while also be a good rewarding thing to change things up when you are going up higher and it gets harder and such which would make relic dolls or epic dolls around with cash increases would be very rewarding

Unfortunately, Epic dolls are kinda subject to the P2W disease. At this point high up in the tower, we can defenitely drop normal dolls and focus more on Divines. We get 1 relic in every new event which kinda shafts newer players. if they only get the rerun. That of course is a problem with the lack of uniformity of events nowadays.

This is a place to give suggestions not discuss negativity on why devs won't add them, please

i feel like higher floors deserve better rewards because it takes more skill to get there, so yeah better rewards would be nice

Scarlet Devil Tower is more about brute force than skills if you were to compare with Element/EX/Divergent Spirit stages.

I still think it should give better rewards the more you go up
Maybe 30 cubes become 60
Maybe they start to drop epic and relic dolls
Potentially even costumes or units who knows
Just an example, but it would make it more fun and less of a slojg

Tower does required some skills, but the general approach is like: find appropriate friend -> break -> nuke -> rinse and repeat. It doesn' reward you for planning a good strategy but for having a large friend base.
Yeah, about the rewards, tower is an old challenging mode that appeared at the start of the game, at that time the most valuable thing is the divine dolls, so they just give them that thing as the prized rewards and forget to change after more things get added

Nothing will happen if no one tries to change things, and the tower is still being updated

Uh, I guess I will mark it as a JP spoiler, but:
||The rewards did improve in Tower months ago, each 50 floors iirc there's meant to be a Relic Paper Doll, and a Divine Paper Doll each 20 floors, I don't know whether it starts at floor 340 or in the next Tower opening (Floor 320)||
