This is another unfinished entry, and I've said it before on how hard I find it to evaluate these. There are certainly some good ideas, but especially in this case there's a lot that's left unrealized.
There's no sound, no animation, and limited graphics in the visual novel sections. That severely limits the appeal of those sections; frankly I found them to be quite dry and boring. I'm not going to harp on this too much, because the game isn't finished and presumably those things would be added later to spice things up.
Having platforming sections sounds fun, but there's only a brief bit in the game right now and it's super rough. The only useful feedback I can give is that the control map ends up really weird on a US English QWERTY keyboard. It seems to be designed for AZERTY or something else.
The visual style is solid. I'm not sure if the backgrounds are actually unfinished drawings meant to be in the same style as the characters, but they work as is. Having line drawings as backgrounds and detailed, full-colour characters works to emphasize the latter.
The dialogue needs work, especially if those sections are going to be the emphasis of the game.
At the very least it needs copy editing; presumably due to being rushed it's rife with typos and inconsistencies. Lulu is explainable as a nickname for Lucienne, but then her name inexplicably changes to Wendy halfway through the game. There's also plenty of inconsistent capitalization, spelling errors, and at least one line of errant commas.
With that aside, the dialogue is clunky and often confusing. Part of this is definitely because of the issues above which make things harder to follow in general. I think the limited graphics and lack of animation or sound doesn't help either. But even with those out of the way, it's just not believable. Characters seem to do things for unknown reasons, they rarely react to new situations the way I'd expect someone to, and I'm still not sure how everything connects together.
The story at its heart is fine. It's not whiz-bang amazing, but it's a decent concept. It's how it is told that would really make it shine or fall flat. I think that's how I feel about this game in general- at its heart there's something there, but unfortunately there just wasn't time to get it all in line and make it shine.
