Nice and spooky. The mood here it's just right and visuals looks stunning. Maybe sprint speed could be set as default one (since there is no reason to not to sprint) and some other parts of level could be filled with some more puzzles. Those are just small things, overall it's really nice game.

so, basically, it's "Adéla ještě nevečeřela, MARS edition"? :D
I like cartoonish graphics with spooky vibes, excelent job.
and sound design is great too, really helps set the spooky mood!

As others said, the game felt a bit slow, even with holding shift the whole time. But i think this fact was greatly overshadowed by beautiful graphics, fitting sound and great metroidvania concepts. I managed to get to the end and had fun :) Good job!

Awesome! The animations are truly great :D
While I love the disconnection between the blurriness of the animation and the slow movement, it definitely could be a bit faster (but I'm reading You're planning that). The music fits very nicely. One thing that bothered me was inability to jump, probably because running up the ramps was so slow without that.

Quite stunning! And the mechanic of watering different flowers is interesting, do you plan to work more on this concept?:)

Beautiful. As I expected of course. 

The world is so beautifull! But the walking is so slow, I didn't have the patience to get further in the game than to the first drop.
