I appreciate wanting to add platforming elements to this, but I have numerous problems with the additions. Sliding is extremely unreliable and frustrating to use- It's unclear what the game considers fast enough to be 'running', and there's an invisible cooldown keeping you from sliding after you get up from sliding, which can result in getting hit while mashing the S key to slide, or getting stuck between the ghost lady in the chase sequence and the ledge you have to slide under because you get let out of the grab animation only to not be able to move and immediately get grabbed again.
It's also buggy, because after getting the game-over where she catches you and restarting, when you load back in she's chasing you again even though you haven't picked up the item she's chasing you for.
I can see what you're going for, adding in platforming elements and enemies to fight instead of just making it a walking simulator with occasional expansion scenes, but the usage and placement of enemies is more annoying than anything and just kind of gets in the way of what everyone's actually here for- Especially with the janky controls and hitboxes, and ESPECIALLY when an enemy can just appear from nowhere and hit you. That's never satisfying.
The extraneous platforming elements show off what could be good (jumping from walls, for example) but the way this level is set up there's absolutely no reason for the player to engage with them. If they want to see the expansion scene when they get caught, they should just stand still; if they want to see what happens when they escape, they should just run to the right while mashing Z.
The text screen for failure also feels kind of... disappointing? The text progresses really slowly and takes up the whole screen due to the blocky font. If a player fails and just wants to try again, it's really annoying to have to sit through that whole thing just to retry.
Also, I'd argue that expansion should probably be a reward for playing well, not a 'reward' for failing the challenge the game's putting forward.
A lot of people probably won't care about these issues but I think it's possible to make a horny game and a good game at the same time!
