>>2293212There are a few more examples like this, and it made me wonder, does an ecchi game really need combat at all? It feels a bit like a formality, and even a potential waste of time and resources.
I understand why these games tend to have combat in them. Most are made in RPGmaker, which is a system designed around turn-based RPG mechanics. You may as well play to the system's strengths. Additionally, there's the idea of pacing as well. If every scene is simply placed back-to-back, then the pacing is messed up and the scenes just sort of blend together, nothing really standing out. Throwing in a few combat encounters between scenes can help to differentiate each one, making them more memorable.
Anyways, this might seem like a crazy suggestion, and it may be completely outside of what you want to create, but why include combat at all? Instead of the heroine being an adventurer, she could be an archeologist. Instead of going through a dungeon to fight monsters, she could go through solving block-pushing puzzles and re-arranging beams of light. If combat isn't going to be directly tied to ENF, it may be more liberating to remove it altogether.
This could even be a story beat. The company you work for kept sending adventurers to gather these artifacts, but they were no match for the puzzles and kept being driven away by the villagers. So they sent someone a bit "brainier" to retrieve them instead.
Additionally, just getting the dungeons to let you inside could be a puzzle on it's own. The solutions might require a certain item you need to obtain from an NPC who only appears during certain days at certain times that you need to not only track down, but convince to help you.
>>2293199 This poster mentioned BotW which has a few puzzles like this, one of which involves standing in a certain place at a certain time while wearing nothing at all. Since this game would already be lewd, we could go much further, possibly requiring a specific pose.
