That was a lot of fun, even with the bug (also impressive you managed to get a workaround in time), I kept coming back to try & get more cards in my deck to verse the different heroes. I great level of variety was achieved with only a few changing variables; which is impressive.
The pixel art worked really well with the style as well. & I'm not sure if there was sound; mine wasn't playing?
Well done on getting it done in time.
