anyone have any ideas of how to cheat this game
All the values are saved in the registry under HKEY_CURRENT_USER\SOFTWARE\SAL\Inkling heroes vs Tentacle
It's per save file, with the save files being marked by the first number in the string.
You're looking for the player stats:
0_playerlevel_charm__h1987299034 this boosts loyalty gains in touching scenes
0_playerlevel_hp__h1917537175 governs your stamina in touching scenes
0_playerlevel_tech__h820575541 governs how much pleasure actions give in touching scenes
Money:
0_money__h3981115141 don't set this too high as it will freak out and cause bugs
Skill points are implemented strangely, they're under 0_skillpoint__h842878632 and don't take hex or decimal values cleanly in the regedit interface.
A value of 00 00 00 00 00 40 AF 40 will give you 4000 skill points, which should be enough for most things.
That's all I could figure out, I didn't mess around with the squid girl's stats, but with infinite money and ~250 charm/HP/Tech and 4k skill points you can brute force even hard mode.
