I just played your Hina and Koishi scripts, and I really enjoyed them! I'll spare some of the details, but for the most part I found them to be mostly pretty fun with rather creative spell ideas.
Just a couple things that stuck out--
The blue bullets in "Bridge to Gensokyo" were a bit dense and difficult to read.
It's kinda easy to have the bullets in "Misfortune containment amulet" to cheapshot you when you don't know what's going to happen. May have her fire the X-shaped pattern first before the cross?
I LOVED the final spell for Hina. LOVED it. I'm a sucker for musically synced attacks :3 However, it dragged on for quite a while. Not that there's anything wrong with that, I've done it myself~, but I would recommend a larger variety of patterns throughout just to keep things a bit fresher. Nonetheless, it was still a very fun spell to play through.
I'll take a look at some of your other scripts when I get the chance, but you're definitely showing some promise I'd say. If you ever get the chance to, I highly recommend making the transition to ph3. I know you've probably heard that a million times, but with your ideas, you could do so much more (and more easily) with ph3. I can't guarantee the switch will be easy though, but it's something to consider whenever you feel like you're being stifled by 0.12m.
