Going off information posted to the relevant bundle thread, this game doesn't seem to have any non-region restricted keys, even when purchasing from regions like the US, so if possible, if you haven't already, you may want to give the game's region restrictions a fresh glance over before the giveaway ends: https://www.steamgifts.com/discussion/llpBX/humble-bundle-march-2023-humble-choice-40

My Taiwan steam account can't activated the key. The key have region restriction. I agree to delete the giveaway.
