I like the chill vibe of this game and the character design and animation are nice! It took me a little while to get the hang of it, but I can see what you were going for with the puzzles, and I actually think there's a lot of potential with the plant/fungi-growing mechanics! It took me an embarrassingly long time to get through the third stage (I kept trying to make it work by putting the mushroom on top of the tree, lol), but I eventually got it. The fifth stage was showing some promise, and I think I figured out what I needed to do, but unfortunately I ran into a game-breaking bug where for some reason the game would freeze and it wouldn't take any input from the keyboard or mouse. It might have to do with activating the "Look Around" mode, or launching plants while in that mode, but sometimes it did work without issue, so I don't know. I restarted the game a few times and kept running into the same problem. Also, perhaps even more strangely, after the first time I encountered this bug, the sound and music stopped working, and then they somehow stayed off even when I refreshed the page and reloaded the game.
Anyway, I don't know if it was just me, but I thought I'd mention it. Overall, very cute game, I like the idea of carrying a rose to your loved one (on your head, haha) being the main goal, and there's some solid, classic puzzle-platformer mechanics in there!
