1. There seems to be a very large difference between melee and magic builds. The damage increase with the magic book and increasing your MP seems to be minimal compared to just swinging my sword, regardless of how I build.
After testing it again lately we are noticing that indeed melee builds are very strong. We are working on a few tweaks for the requirements and the general builds to make them more balanced.
2. Progression seemed to be really fast , although this may be just because I got lucky. I went from having to kill things by jumping back and forth with around ~20 damage per hit every second or so to finding a "Thousand Blades Sword" that boosted my damage to 96 and I was hitting with attack speed 90, making me nearly unkillable. At that point I went through and killed every boss within 30 seconds.
Sames as with number 1, we need to balance the drops so you can't get those kind of items so quickly. Luck is always a factor but it shouldn't be that easy to kill every boss.
3. Is there somewhere to find information about skills or abilities? Most of them do seem to be self-explanatory, but for some inexperienced players it may be a little confusing. Maybe a tool tip in-game would help. Currently I do not know what life-drain or ghost dash does.
Yes! we will be adding better descriptions on each skill, the game in general lacks tutorials and information.
4. Is there any point to having more adventure points? I seem to have over 1000 right now and I don't really see a use to them after getting all your skills. This is fine I just was wondering if there is a further use or plans for more.
Once you got everything unlocked with your adventure points there is not a lot to do with them. We should think of something for those cases. I think that you should be able to face the Formatter by now!
5. Is there a difference between the elements and how they work with elemental equipment? I haven't found a reason to switch my element for any reason besides changing my color.
The elements are similar to the elements in pokemon, if you are a leaf type and you get hit with fire you get double the damage. Unfortunately with how the game balance is right now I don't think there is much difference, but it is mostly if you want to clean a particular kind more easily.
