Oh, Unreal definitely is a powerful tool... And because i came from blender the node-based blueprints Editor already felt familiar... I also considered using JMonkeyEngine because I'm Java Native Speaker, but I decided on unreal at the end because I gotta learn C either way and the engine definitely seemed more powerful xD
My personal aim is to get to know several alternatives and be good at those that differ the most, so that i can decide which one I'm using for the game I want to make and what fits best... But one thing at a time...
Ah... THAT dead end xD You think it would be better to let the player also use the filled vase instead?
