This game's strengths are the monster designs, the graphics, and the regular isometric bullet-hell gameplay.
I found the turn-based mode to be a bit confusing - the UI is a little tough to manage - having the cursor switch from the target to a mouse cursor would have been helpful. There's also not much feedback for what happens in turn-based mode, so there were some times where I would end a turn, and then all the enemies would despawn because I had killed enough of them to enter the boss phase, but I thought that I had killed them all with the multi-target attack.
I would have also preferred a downloadable version, as the UI is clipped on my screen and it wouldn't let me enter fullscreen mode to try and fix it.
Overall, really nice job, I had fun dodging the bullets :)
