Here's my translation file (goes in main folder >BepInEx>Translation>en>Text) I didn't touch any of the dialogue, but I cleaned up the UI a little and made some of the skills easier to understand.
To make the game much easier, get 'disturbing' off the upgrade menu right away, it allows you to erase all crosses in a room for 1AP. Once you unlock the 'blame' action (it's a red icon with a white tongue) you can use it to remove 5 crosses from one girl per turn. If you don't drop any girls to 2 hearts, they'll stay at 100% resist to blame so you can use it to remove 5 crosses every turn. With the ability to wipe away crosses you can keep the count low.
From there just tidy up crosses each round and try to keep a few AP in reserve, as you'll get 5 upgrade points per AP that you haven't used at the end of a round. Then it's just a matter of grinding to get all the upgrades.
For the skills, my end game build was 3 Pulsing II, 1 Patience III in the middle tile (so it's always available with master skill set), Intimidate and Impress to remove skills from the bottom and top of the girl's queue, Attack boost II, and then two Observation II for free damage. Once you get the full 5 stacks of attack up Pulsing is a massively damaging skill, and with Patience at 100% uptime you can tank most things. Just remove any dangerous skills with Intimidate/Impress and you're good to go.
Also, the red pips (unlocked with the Excitement upgrade) top left of your skill panel refresh all skills and give you more SP. They also refresh the lockout on Patience/Intimidate/Impress, so you can get out of bad situations with those.
Anyway I may come back and look at a proper translation later, but this already took longer than I'd like. It is a fun game though.
