Played the demo. Design is amazing, script is a bit cliche but not too bad. It's a shame that the only lewd scene available in the demo is very tame.
Don't get me wrong, I'm sure it's a great game past the demo but without knowing how it really is, I can't say it's worth getting the full game. Especially with the horrible rng with the boss. There's not a guarantee you will win. I have beat them but it takes several tries even though I understand the battle system. It's completely up to rng.
Anyways, love the design. Wish there was more available in the demo. To those reading, if you have the money to spare then I recommend buying the full version to experience it. I'm on a very tight budget so I can't.
Thanks for taking the time to read!
