Thank you!
Yes, initially the game can be quite overwhelming. But after the initial learning curve new highscores should come naturally. ^^
Really cool concept for both the "Support-" and the "Only one Shot"-Theme! I was just barely able to defeat all 5 stages with a sliver of mana left. The game could definitely be expanded in interesting ways, like getting to add members to your party, different battles, skills, upgrades etc.
The barrier-skill is a little bit too strong i think, as just tapping the button clears all bullets within range, so I was able to preserve alot of mana that way. (But I'm also not sure if the dragon can even be beat without that xD)
I would also say that the dragon becomes a bit too tanky in the later stages, as the gameplay doesn't change over the run.
Also I think there needs to be at least one attack that cannot be blocked with the barrier, like the dragon smashing into the party either on the top or the bottom of the screen, so you have to move out of the way.
Overall though really fun game, good job!
