I beat my record, now I'm at 375 feet! But then I got stuck in an inescapable spot again... it's my bad, but it was a shame to see all my amassed stamina go to waste. Maybe if you update it in the future, you could add an extra button that spends 10 stamina to move one tile backwards? That would add an extra layer of strategy and be a huge lifesaver! But anyway, you already made an addictive game, so congrats :)
