I have to say, it's quite frustrating that the game doesn't have in-game saves during battles. While I understand that most roguelite games lack mid-game saves, it's a pity that this game requires constant combat with little downtime to appreciate the protagonist's illustrations. I think it would be a great addition to include a town scene where players can interact with the protagonist during non-gameplay time, applying different effects based on the protagonist's level. On the other hand, I'm not sure if it's because I'm playing the free version, but the lack of progression outside of battles, coupled with the relatively long duration of each game session (especially considering the protagonist is a solo character with limited tactical variability), makes the early stages of the game feel incredibly repetitive. For instance, for a prolonged period, your deck building remains rudimentary, essentially revolving around choosing between defense and offense.
It's not because your playing the free version, it's because it's an early build. I'm aware content is currently limited, and more content is gonna get added. That includes floors, scenes, events, items, cards, enemies... The game is basically in a proof of concept stage.
Also, the game does have ingame saves... Were you talking about ingame *scenes* maybe? If that's the case, they're absolutely planned. Just not for this first build.
