I think the graphics are clean, the characters are adorable and the gameplay premise of clearing the node maps and upgrading gear to be potentially compelling.  Both of my complaints may be fixed by release but here they are.  First, it felt a bit too grindy without enough payoff to make the grind feel good like it does in some games.  I suspect that as levels, gear upgrades and other RPG systems get introduced that this is a non issue.  The other complaint is about the adult content in that the animations just aren't enough to excite me at all or they might of helped make the grinding less of a chore.  I didn't get to any scenes between the main characters and only seen the crystal animations.  I may be too jaded but those didn't do anything for me despite being cutely drawn and animated to a mostly acceptable level.  Making this post mainly because those scenes look like they might take a degree of work and yet I think typical VN H-scenes with variations on stills accompanied by dialog would evoke more eroticism.  I've seen games where animations worked but my first impression here was that its just not enough of a carrot.. to make me want to continue playing.

Feel free to delete this post after its read if thats a thing you can do.  I don't want it here, will never return to check it and only posted it to try to help
