Interesting game! It was fun to play, maybe I would add some fast forward or skip button for when we collect the attack points, etc. Also, I would change the mechanics a bit so that all the attack doesn't get wasted on one enemy. It would make sense if it were a bit more strategic, but because it is almost pure RNG then it would make sense to add some strategic element to it, or make it attack the whole group.
If there's time I would add some settings for volume, etc. Other than that, I liked it. Simple and effective.
