Pretty fun. There’s two countdowns, so it fits the theme; the first is just the usual boring “oh there’s a timer” countdown, and the second is the dragon chasing you which is why the creativity is so high.
Although, if you go for the speed upgrades asap like I did, then you basically become unstoppable- especially with the decoy upgrade, you can constantly throw and re-pickup your least value item to just keep the dragon slow.
Also, if you have any backpack upgrades, then you need to buy stuff in order to have room to sell stuff.
