I tried the fixed version and I just have no words to describe how hard it could be the jam version, typing ATK over and over again was tiresome enough, no wonder how a lot of "spark"would feel XD.
It was fun in the end, I really had to be precise enough and I had a great time, but the level was too long and I was pretty tired before the boss fight, considering the jam version wasn't that complete, well, it really missed the last part, but yeah, as a concept it could be developed quite nice.
