Oh hi thank you for commenting Amigo121. The invisible walls is a glitch with the tile map and was actually fixed, but the work was scrapped because the engine I was using couldn't read the file. Also the thing under the HP bar is like a score counter where you kill enemies or like gather ingredients your score increases. This was supposed to be in the game but was scrapped because of the same reason for the invisible walls glitch. The game will be updated at a later point with the glitches fixed.
