Thank you for taking the time to help sort through my confusions! While I cannot speak for everyone else who has done some grinding in this lovely game. I can say that it just goes to show how well made it is. (Though I was also curious to see how OP I could make the protagonist.) It has left me with a desire to play more, yet of course. I, like everyone else, must wait patiently for further updates.
I also like the idea of a checkpoint system in this game. But feel as if it's not entirely needed, if that makes sense. If anything you could make it optional. OR perhaps in the form of an item?
1 last thing I would recommend is better balancing on armor/clothing. To be specific. It's a tad annoying to have every piece of armor being 'broad' in its coverage. I think it would be more fun to have specifics instead. In other words. Instead of having ATK, stomach strength, life and vore skill. It could be just ATK, DEF, life, and possibly rupture chance/DPS. That way people aren't hording 3 sets of gear. Because 1 set has good capacity and acid DMG but is muddled with rupture boosting stats. Another set has good ATK but doesn't have rupture boosting stats.
I'm aware it's also because of bad RNG. But it does feel as if none of my armor has explicitly. 'Boosts all vore related stats to better yourself as a stomach-based warrior'. Just broad coverage for all styles of fighting.
A neat idea to also toss out while on this subject. Armor that is a 'grade' above perfect, but isn't quite simply OP. In the event that all equipment remains broad in its stat boosting. You could at least add specialized armor's dropped by optional bosses. Best example I can give is of course, the optional boss of stage 4. Dropping an 'entire set' of rupture-based armor. Every time you beat them, they drop a singular piece of the armor. Which only boosts rupture chance and DPS. By a fair bit higher than what you might get from 'perfected grade' armors. That way it's risk/reward so to speak. Do you boost most of your stats for better survivability? Or go all in on specialized gear that forces you to play by its rules?
(I also think it might be neat/unique to add a function or skill. Where the protagonist can swallow a piece of armor. Which would temporarily boost their stats. According to the armor's 2 highest stats.)
