It looks like literally every other disgusting moe noise box ever but on top of that the gameplay's trash.
If by classic you mean outdated game design that's aged about as well as Kevin Spacey's films sure, the fact that it's Game Over Rape only adds to it.
Everyone loves to replay content to get like 5 variations of the same image that took all of 1 day to draw from bases found online.
As far as tastes go I played Bubsy as a kid and I didn't want to gouge my eyes out like I do nowadays.
Heck, I liked Sonic 06 but holy shit.
I get it you don't like it, and i can't do anything but respect you (hey, you liked Atelier Tia, which for my tastes was pretty subpar and a waste of potential), but whatever you mean by "every other moe noise box", please point out any of those, because i'd love to find a similar one in terms of the voicework and animation.
(And actually, i've found this style is similar to those of the packs of animations one can see being released constantly in the discord server, those of pixiv or japanese artists with l2d animations and voiced, but still this length and quality of dialogue is still not easily rivaled. It's in h games where there is nothing similar).
Now, don't get me wrong. I agree with you, this is one of those cases of ERO on top of game, and not the other way around, a Game with ERO content.
I just hesitated to say that because tower defense is pretty much always anyways (and so are h games generally speaking). So, can't really say.
Anyway,
OP might want to add the following tags:
Combat, Monster
