So happy you liked it 🤗 The two missing upgrades might just be a matter of the right position. You have to stand more to the left in both cases, as they are upgrades for the fence and the temple. The collision window is in the center of these two objects. Kingdom Two Crowns was a big inspiration indeed, the second one is this little gem here https://alexanderperrin.itch.io/short-trip But Rollercoaster coud definitly have served as one as well. Thanks for playing!
