Thanks Tylak for downloading the game. I loved Boom Blox on the Wii but it wasn't my intention to replicate/remake it (at least not consciously!).
Yes, perhaps the instructions could be a bit clearer with regards to the 'bucket' and it associated target to empty it.
This is still a WIP so things will most likely change in an updated future version with regards to scoring, additional weapons, game zones, obstacles etc.
