This was a great entry in the Magical Girl Jam. I'm glad to see you're still doing great work!
"It would have been nice if getting all the crystals unlocked some secret ending or something different" - AAAAAA it unlocks a secret boss if you go back to the statue! And the controls are configurable in controls.ini. Good little vid though, sorry that my game frustrated you... glad you played it!
Oh dear. Well I went back, the added controller support was the perfect fix for the controls.
I didn't notice the eyes of the statue glow for a second when you pick up the crystal there.
The additional boss was nice extra content, although their screen clearing move was hard to discern. It took me a while to figure out why I was even dying.
A little frustration is perfectly acceptable. It can even add to satisfaction of overcoming the challenge, so long as the player is able to tell why they failed, learn from their mistakes, and feel their progression with each attempt.
I'm happy to have played it, and again I can say, I'm super excited to see what you do next. I love your content.
