Beat stage 10. Doesn't seem to be an end, and the waves can take a while at that that point, even with my formation shot linked to a mine spell with both mirror shot and quad shot and magic laser.
The game was fun, but I feel like mine shot or diamond shot attached via trigger spell to a rapid-fire attack is kind-of the only possible strategy because of the damage difference between those spells and everything else, which lessens replayability a bit.
Still, it took over an hour before I gave up hope for an ending, which, especially considering the limited enemy designs, means it must have pretty good core mechanics or I would have left earlier. Also the graphics for the attacks are pretty great; it's neat that you-- even at the start of the game-- fill the screen with colorful attacks, and that the enemy attacks and sprites are mostly still visible through it all.
