I created this mainly to put into practice things I learned from tutorials. I will leave it as it is for now in order to learn more and create better games in the future. Not going to abandon it completely, as I really like the concept. I might pick it up later in the form of a sequel or something.
Thank you. The structure, like walls, pipes, colums and also the monster were created in Blender. Some of the smaller stuff like the barrels or palets come from a free asset pack for unity.
