I have played the game, and it seems interesting to have a DiD game that isn't made in RPG Maker like Didnapper 2 or in 3D like Eternal Dread 3 being made in Unreal. A Didvania is something that is unheard of and is interesting twist to the DiD game formula.
Anyway, there are some things I noticed:
- The game's page has an 18+ warning similar although I haven't found any 18+ content similar to Didnapper 2. I don't know if 18+ is given due to bondage.
- Enter doesn't advance the text. Only Space does.
- Although A and D moves, S doesn't crouch, and W doesn't interact or aim the whip upwards.
- The game never tells you that bindings are determined by health (Silenced when reaching 4 hearts, Defenseless when reaching 2 hearts, Bound at 0 hearts).
- You can't attack when reaching 2 hearts and you can't talk (i.e., freeing damsels) when reaching 4 hearts.
- Whenever you load the game, Vivi must break the cage. The exception is the save point in Rosaline's/Mistress' room.
- There's no game over or being sent back to the save point on "death". Instead, you must struggle and escape the bondage.
- Interacting with the save point but not saving doesn't restore hearts unlike the Metroid Prime trilogy and Bloodstained: Ritual of the Night, only saving does. Saving also doesn't remove the statuses like bindings and gags.
- Stamina decreases when struggling even when not holding down (or mashing the button).
- People have mentioned you can get stuck in the area with the two damsels and the Slime Girl since the platform is too high for Vivi to reach. This also means you can get stuck if you skip the scene with Rosaline and head down to the area.
- The download is not marked for Windows. This should be clear as some people with Mac or Linux have asked if the game is available on those OS.
I initially found the required struggle sequences with Rosaline and the maids or being pulled by the enemy difficult because I didn't realize I had to hold down the button instead of mashing it. The Slime Girl could be hard if the player doesn't know you can hold to escape bindings or press X to cancel escaping.
