I chose to look at this game because it was in the pirate software game jam. You really demonstrated the theme of 'spreading'. I liked the progression system and reward, my favourite was discovering all this while doing a chill relaxing activity. This brings me happy memories as I liked to blow the seeds off the dandelions as a child. I came back to look at the game again after the jam was judged as you said you might make some fixes.
Thank you for making this game and keep having fun with game jams.
SPOILERS: My feedback: on my first play I couldn't find a final collectible. When I came back now I found them all because I looked for them first before blowing dandelions everywhere. I think I couldn't see it in my first playthrough because I filled the arena with dandelions.
