I absolutely adore this game!! The race got bugged for me though I couldn't find any other rectangles it made me really sad I couldn't complete it :( The pixel shader was very charming and I loved the ragdoll feeling of the movement! I think you did an amazing job! Only thing I would recommend is since there seems to be a minimap, maybe include a big map that can be opened with 'M'? I had a tough time finding the boxing rings in order and maybe the blue rectangles for the race could be found on the big map as well?
Awesome awesome job though I loved playing it!
