Being able to click in between two tiles in spelunking for 1 stamina is great. What’s not great, is that the click “hit box” seems very small and inconsistent. Taking a few extra seconds to try and perfectly line my mouse up to be able to click two tiles for the cost of one and then missing is the most frustrating and unnecessary feature with spelunking.
Remove the double tile click or make it more consistent. Could even add it as an upgrade so everyone knows you’re able to do it.
