Hi there! Awesome game so far! The images and animations are top-notch and every scene where the superhero gets kneed or kicked or punched in the nuts is so well drawn! Characters are beautiful, world-building is deep and has potential for more. I ran into the same bug mentioned above, where winning (and losing as well) from the gymnast turns the night into day. It was Aika specifically, if this helps you debug. I think this may have also happened after fighting Emma (blue dress lady) and losing.
Regarding the QTE,I also agree that it's too hard right now and would welcome the change to just arrow keys. Having them as QWXZShift means having to use your pinky for 6-7 keys in quick sequence which made it nigh impossible lol. It actually led to a funny scenario, where the only reason I won against Aika on the first night was because she distracted me and kicked me in the balls instead of knocking me down with her slide tackle move. As the game is right now, it's easier to get up and fight after receiving a devastating ballbust than it is to stand up after getting tripped loool. When I fought her previously, I couldn't get up after she knocked me down because of the QTE and lost. When she kicked me in the balls, it did a lot of damage but I was able to survive with like 50hp and then heal and fight right away, so eventually I won.
Speaking of which, are there any plans to deepen the mechanics/reactions after being ballbusted? I was thinking it might make more sense to have the "standup" QTE be much easier, but add like a "recover from ballbust" QTE that is a bit harder, and uses willpower (to heal your balls, basically). Just feels like when I get ballbusted, it does a lot of damage but doesn't seem to be that big of a deal otherwise. I'm not stunned or debilitated like the Guardian was after a single kick to his balls. Especially in those two-on-one scenes where one girl holds you in an exposed position while the other kicks or punches your balls. It would be cool to have a QTE or struggle scene/mechanic to get out of that hold, and to overcome the ballbust pain, instead of just refreshing to the normal battle screen. It might lead to a lot of scenarios where if you get kicked in the balls, you're very likely to lose the fight, but maybe it could be balanced? Maybe if you succeed the QTE you get healed a bit and get up to fight, whereas if you fail they ballbust you more? (I personally love the idea that superheroes are still men in the end, and are extremely vulnerable between the legs, so even they can be taken down easily if they mess up and get kicked in the balls).
Also, it feels a bit too easy to avoid ballbusts because you just have to use "Focus" to get rid of distractions. Might be interesting gameplay-wise and lorewise to make THAT a QTE, similar to when you're trying to avoid climax. Focusing is tricky when there's a hot babe in front of you! Would make it less trivial to avoid a ballbust, with the added thrill of "oh crap I missed the QTE, now I wasted a turn and she's gonna kick me in the balls." It would feel like I'm The One and I, personally, just failed to focus myself and now I'm going to suffer consequences.
Anyway, I've rambled on a lot here, but that's just because I really love the game so far! Also, I don't know if this is a bug or intentional, but my HP is not healing after every battle like it says in the tutorial screen in the prologue. Another bug is when I die and it's loss (1/3) or something, my HP is refilled by my willpower is still 0. (This was after winning the Aika fight, and it had switched from night to day. I died on the next random encounter lol). When I lost to Emma before, it refilled both HP and WP so I'm not sure what's supposed to happen. I'm playing on the latest version from the google drive, v0.012, downloaded/installed from the 2.85GB file.
You've done a great job so far and I look forward to seeing/playing more!
