Great story premise, nice art/sound combo. The teams worked well together on this.
Found it a little tough for me, especialy at first.
Having NO idea what the controls were when it started, I figured out how to move, but everything I couldnt do anything else. Wasn;t until I check out key bindings, that I discovered attack, dash and bat form.
Got a little tough for me come Hat boy. Perhaps others are better suited at this then me :P, but i'd recomend starting even easier (especialy in Jam games) and ramping up difficulty steadily.
Well done to the whole team on this! Great work!
