Wow.
Was all of this original? If so, quadruple wow. Very nice attention to detail and amount of design put in. Personally it was a hard time making 2-3 sprites, can't imagine how much time it took you for all of this combined. Did you have a team?
Thanks so much for playing! Yes it was all original - the 2d sprites are based on 3d models. I modelled and painted the characters in Blender first, then animated it with Mixamo, then, in Blender, rendered the animations in 6 directions to make the 2d animations. I had originally planned to make enough characters for 10 levels but I only had time for 3 levels. It was still quite a lot of work though! We are a team of 2 - I did the art, audio, and story and my team mate did the programming. Thanks for your feedback! :)
