I love that you made a game with meta-progression, but it feels like the time it takes to earn enough currency to upgrade is a bit long. I also think that the game should pause while inside the crafting menu so you have time to read the upgrades. Lastly, the ledge-grab feels a little inconsistent and I found myself mashing W and Spacebar at a ledge and still falling to my death.
All that being said, I still did 20 runs in a row trying to get further, so you definitely have the core of a good gameplay loop!
