I wasn't really able to make progress due to the parkour system and the high upgrade cost.

Quick feedback;

• I found the parkour to be quite frustrating. Not every ledge seemed to be grabbable (or it has very strict conditions) and wall running requiring two keys was inconvenient.
• The alloy values are far too low compared to cost of upgrades. Either lower the costs or increase alloy values.
• Maybe randomize alloy locations and have some high value ones that spawn in harder to reach locations (or are hidden in hard to spot locations). That way runs don't involve revisiting same spots.
• Without upgrades there's a lot of dead end paths. I also feel the floor should instantly kill the player without upgrades as often there isn't even a way back up anyway.
• Performance seem to dip in the warehouse
• Just show the upgrade menu between runs, no need for that confirmation prompt. Though I don't think it should be shown before first run, as player obviously won't have any alloy.
