Oh, no I have everything, but I feel like there should be something after Loki, so I'm still messing around with the game to try and figure out if there is :P
Two potentially useful tricks for other people;
If you're losing your opponent, spam W. You'll always know where they are, even in the thickest cloud of bullets.
Also, whenever you chain 200k or more, get hit. Even if you have time slowed, or whenever - you'll pick up 50% Drive, which opens the possibility of using your Drive DURING your Drive! :O
You get Excalibur for I believe beating Act 19 using the first weapon.
More importantly, you unlock Loki for beating Loki, which is clearly the best. Best Overdrive, best damage. Just don't get hit (or do!)
It seeks easiest to beat Loki if you hand to the corners of the screen. Like, instead of trying to weave through his bullets (which also works) try to avoid the entire spray altogether.
xkyo, you have to beat Stage 5 without getting hit.
Anyone know if there's more than just Loki for bonus? I feel like they left 2 more slots but aside from something ridiculous like perfecting the last stage, I'm pretty sure I've done everything.
A few suggestions!
1. "Invisible" shouldn't make you immune to getting hit - but a word like "Immaterial" would work, definitely!
2. I would really like if (either when you add music, or with a slight graphics tweak) you would perhaps blink, or something to give you a notification that your power-up was going to wear off.
Otherwise, it was really nicely put together! I think some graphical touch-ups could help it, but it's definitely fun :)
This really is rough - you took a genre that generally has a smaller, more hardcore RPG fanbase, and put it in a very public setting. To be honest, I'm surprised it's as well received as it is - don't get me wrong, I love the game and it's well made, but as I'm sure you can see from most of the comments, most of the users aren't really your target audience.
That being said, a few tiny tweaks would be wonderful. Auto-ending the turn when you're out of possible actions, adding a hotkey to ending the turn; Those would be nice. Otherwise, I'd have to say keep up the good work!
