Version 2.3
I'm skipping most of the stuff I've already seen.
Don't Know
Spell - Curvies are too random. Too many walls
Spell 3 - Trollish
Spell 4 - Hina Ripoff
Spell 8 - Nice. The ideas is good. This would be a good spell card.
Spell 10 - Makes a good non spell
Spell 11 - Too much delay w/o bullets
Spell 12 - Too easy once you understand it.
Spell 13 - Overdrive Mode. Way too hard.
Spell 14 - Super hard but a good non spell.
Stage 1
Starts off meh.
Immediately Post-midboss, WAY too repetitive.
Post mid boss, some of the laser enemies fire SFX but no lasers.
Stage 2
Opener is way too long and too random. Also, enemies have too much HP.
Post mid boss, much better. Very nice, except that default player attacks obscure enemy bulets.
Stage 4
Once again, too much Enemy HP.
There are still random bullet rings from the ceiling. Fix this. (Pre-midboss)
Enemies are not deleting correctly off of the screen.
Stage 5
Still too many walls of orange bubbles.
Stage 6
It's taboo to have bullet bounce off of the bottom of the screen like that.
Also, can't tell the difference between enemy graphic and bullet graphic.
ALSO, opener is WAY too repetitive
The honing section is bland. Use different colors.
Also, you made a common error. When enemies delete, object bullets created by those enemies automatically lose their properties as object bullets. So you really need to make the bullets never have a speed of 0.
Post-midboss death fairy: Way too much HP. Way too repetitive. Boring w/o SFX.
2nd death fairy has same problem.
End of battle final spell isn't very appealing. Also, the effect is too dramatic, and you can die in that time span. Don't do it.
Overall, the music is really not good at bringing about an exciting feeling to the spells, the SFX are artificial sounding and don't sound great with your music, your lack of enemy graphics isn't very appealing, and your patterns need both bullet variety and color variety. You still have some residual errors, and you still need lots of work with the flow of a stage.
I'm going to make an offer to you. Provide me with a full script of your game with all of the characters, their names, their spell cards, and a plot. If you can do that, I will offer to help you script a player character for this game if you want. As in, a Non-Reimu/Marisa. Other than that, name your stages, get backgrounds, and name your attacks.
Oh, and you should definitely try and make your music more catchy and exciting.
Also, 0.12m doesn't like .ogg files. It crashed automatically when I tried to use them.
