Pretty fun game!
I like the concept of being a seed and growing into a new sunflower!
Some suggestions for improvement in case you want to polish the game a bit more:
- Avoid spawning a rock right in front of the player start position. It makes the game feel unfair.
- Save and display the player's best score in the title screen.
- The audio settings are not saved. After restarting the game it goes back to 100% music and sound.
- Related to the previous point, it's a good idea to have the default volume at maybe 50-70% to avoid blasting the players speakers/headphones on first play.
- The feeding sfx is very loud or the sfx volume setting is not working.
Keep up the good work!
