Probably the best game I've found on this site, I have very few complaints about it.
The gameplay itself is super unique and surprisingly fun to play, though there are some problematic encounters like with the Imp, where sometimes the screen just becomes impossible to do much of anything on when you start getting the giraffe shapes and honeycomb gatling gun things that already eat a lot of the playable screen space for your heart, but then the Imp goes and spams massive lava balls that make it even worse.
Art style is beautiful, and the scenes are stunning, though admittedly traversing the map becomes a chore when the places you want to go to are far apart with a lot of stop and go movement. It'd be nice to have the option to just click on a part of the map and automatically begin traveling to it without interruption, especially when going long distances.
Leveling characters can be very grind intensive as well, and apart from stat increases I'm not sure entirely what levels are for other than as a progression system to slow rank ups on characters.
Other than that, everything about this game is superb, I do want to ask though, will we be able to take save data from the demo and begin where we left off when the full release eventually comes out? From what I understand the demo is like, 25-ish percent worth of the full release, and I've put in a solid 10 hours of playtime as of writing this comment, I'd love to be able to keep all the progress I've made thus far.
All in all, fantastic game, eagerly waiting for updates on it, even considering joining the Patreon to support it
Edit: Just finished the Demo, and I think I found some bugs. I didn't get a power orb from beating Nightmare, and I'm pretty sure I'm now softlocked out of being able to max rank my characters now, I might be in some sort of limbo state of pre-post demo, and post demo. I'm not sure.
