Unable to play

Great game but unable to get past loading screen goes black

It‘s great, but it could be so much better

Firstly, the rogue-like horror story aspect of this game is phenomenal. The combat system, even more than that, is its greatest strength. It’s what differentiates this gacha game from most of the others with the way it’s done; it’s very interactive, strategic, and aesthetically pleasing. There’s a lot of uniqueness this game provides that makes it one of the most unique in its own right, like the trauma system.

However, even though revealing clothes is very common for female characters in gacha games, it’s just off-putting in a game like this that’s supposed to be more serious. More despairing, and more ambitious. The storyline was fantastic, especially at the beginning when you’re first starting. But as time went on, and especially in present times with more provocative female characters… it’s not working out. Do you know how amazing it would be if the storyline got even darker, and if new characters being released had more personality, story, and goal than just their bodies being revealing at every movement? This game would skyrocket in value. It’s that good otherwise.

Please. PLEASE don’t forget the potential this game has beyond typical gacha objectifying women. Please.

Chaos Rewards Hero

This game has so much going on. At first the learning curve is pretty extreme with all the upgradable stats and multiple menu screens. Thankfully there are tutorials to guide you through the options and a helpful Help section that covers all the details you may have missed. As far story goes it’s fair but there is a lot of voice acting that makes the quality of the overall game pretty expressive. Character design is rather “ecchi” and if you know what that means you probably are already playing the game.

All in all the game is fun to play with generous rewards, seasonal events, plenty of combat engagements to test out your teams and robust in the customization for skill progression and characters galore.

Jiggle physics

I haven’t played the game yet but the red hair girl god jiggle physics 🤤🤤🤤

Just short of p*rn

It was a promising lovecraftian horror roguelike akin to Slay the Spire. The Korean fanbase was upset another male character got more female attention, so the devs responded and now only the protagonist can have any kind of relationship with anyone. So one guy, a room of mostly women and some men facing horrors, seeking comfort. The gameplay felt unique but not the kind of game I’d want to play in the breakroom.
