Finished it. Lovely art, but the story kinda feels really rushed and i couldn't find myself attached to any of the characters, except the MC. She's a decent MC, has some snark and kinda nice personality but every one else just passes by, their interactions only last one moment without time to to familiarize with them at all.
Compared to recent games i played like lacuna, there are attachment we feel for the characters, and both the recurring and one time characters feel fleshed out, in Sundew, they just feel like props to move the plot instead of actual characters. There is a weird feeling that the developer has established foundations of great cast, but after 1 interaction, they're all completely gone, never to appear again.
I also "get" the story, and there are some nice concepts and ideas, again it's not well elaborated. The actual story is nice, but it’s told rather poorly.
Is it worth playing? Yeah. It's fun and competent enough for a 1 woman project, and the asking price is pretty low. The atmosphere, style and visuals are top notch, the puzzles are standard, and the story has some great concept with lacking execution.
