Yup, tried out Uppers briefly. Looks even better visually than VD does. Really slick visuals. The game is gonna be less import-friendly, though due to the girls cheering on the sidelines. They want you to do certain moves/finishers to gain their favor in battle, and you'll need to be able to read kanji to understand them all. I don't think it's enough to stop someone from playing though.
The character models are really nice but is really jarring the way most girls in the sidelines are stuck in a loop making them look like gifs rather than character models.
Uppers is an old school beat 'em up. Literally.
You just move through the level and punch dudes, you can pick some elements in the background (like bikes) to use as projectiles and your health ups are the girls. The girls ask you for some specific actions to met before they cure you (like beating three mooks or using three times the throw).
The game is indeed very slow paced and enemies rarely attack, I had to stand still in the middle of bunch of mooks for five seconds before one enemy finally decided to attack me, and even then, there's a green spark surrounding them just before they move, making incredibly easy to avoid the attacks.
At least with the characters in the demo, there's no real difference between them beyond their animations and design, they play exactly the same. There's not even a movement list you just have to mash square and the finisher will come on its own. You can access a sort of powered mode but other than making more flashy your attacks and allowing to tag with the other character at the end of a combo doesn't represent a significative change to the gameplay. You have a block button at your disposal and a dodge mechanic similar to Bhikkhuni's but the enemies are so harmless that is pointless. And remember how Nicole could run through the walls in the videos shown?
Is a shared mechanic, you just press x close to a wall to do that. Other than looking cool, there's no real reason to do that in the demo.
Despite the game slow pace, camera can be a pain, the stages have some destructible elements (like walls) and thus, is pretty easy for the camera to get stuck. Virtually any element is able to block your sight.
Levels are big and there are different areas to explore but there's no map t speak of and the only indcators of where going are the groupies. However, there are sections where the stage is barren, making kind of pointless to diverge from the set path.
Depending on what you do during battle, you can trigger a short minigame (for example getting a gust of wind to lift the skirt of three girls) where you have to mash a button (usually circle) at the end to win. Pretty easy but it breaks the flow of the game, and just like the clothes ripping cutscenes in SK, it gets old fast.
Overall is a decent but very mediocre game that other than giving you the chance to show off/perv on some virtual girls doesn't offer anything of note to the genre.
