Loved this so simple but so fun. The one thing i would change is the dash, instead of pushing the dog forward i would keep the particals and the sound but move the frisbee backwards. Right now its a bit hard to collect the last bone you need. My record is 12209
I considered having the dog move slightly right and the frisbee move slightly left, and when they are aligned they don't change position anymore, so when you're perfectly centered, you can go for it.
Alternatively, I would've provided indicators for when you're about to get treats, since it does take some quick reaction to grab those last few.
Ultimately, I felt it offered enough challenge to be fun and still slightly difficult. There is a fail state for the game that's not hard to achieve lol
