The art is super cute! Though the gameplay is a tad rough; here's some suggestions I have:
1) The movement seems super slippery, even without jumping. It's this slippery-ness that's caused me to slip into lava too many times, even when I've stopped hitting any buttons. Maybe try toning down the acceleration a little to give the player more control?
2) The jump is super jarring and fast. I'd recommend a tad more floatiness/acceleration to it; the jump combined with the already-slippery-ness makes some easy jumps super hard to do.
3) Love the parallax in the background, but it's a little too fast for me. Maybe make it a little slower?
4) This is a bit of a nitpick, but some of the ledges have a "lip" that makes it harder to jump on; I think the aesthetic is nice, so it's more of a collision shape fix than an art fix.
5) Finally, this is very much a personal preference, but maybe consider having the jump button be controlled by the up arrow key/w key instead of the space bar? I dunno, just a suggestion you can play around with.
I liked the art, but I especially loved the particles that you used! My main gripes were 1) the D (right) button didn't seem to work for me (WAS and arrow keys were fine on keyboard, but when I pressed D, character didn't move) and 2) the keys Alt and Alt Gr are pretty far away from each other on my keyboard, so it was pretty difficult to switch between them during combat (these were all using the browser mode). Otherwise, great game!
The game looks really great! The only things I would recommend is 1) a controls screen or just a short description below the page specifying that it's WASD to move the flower and 2) Maybe have that distance number appear on the game over screen in a format like "You've passed __ obstacles!". Otherwise, I really like the graphics and the sound design!
