You want to know what could be made better? How about this:
- i love ranged combat. Hit'n'run. So i've chosen fireball and heeling staff. Ending without any mana left after destroying the 3 crystals at the very beginning and facing the first enemy. Bad, really bad thing to leaf the player without any mana regeneration and not mention this at the beginning. I had to start again creating another weapon set. I couldn't even flee since the crystals resporned after leaving and reentering the room. And without mana i couldn't destroy them.
- having a sword and the healing staff now, i started playing. Sure, the green area marking the enemy attack is a good idea. But not being able to escape once i have started my own attack is pretty bad. It should be aborted when i run too far away.
- since neither mana nor health regenerate and there is no rest function to fill up both it's just a manner of time till i was hit so often that i have no mana left to heal myself. compared to the fact, that enemies resporn every time i enter a room ... own health limited but endless enemies? how did you thought that would work???
- last thing i had till i hat to reload the 7th time without getting further the first 3 rooms and decided to write this: in the room behind the crystal are so many enemies - it happened multiple times that they surrounded and blocked me. And since health is the most valuable thing in your game it's no mater if i can free myself or not. Once surrounded for a short period of time too much health is lost to continue playing ...
And that's why the game is pretty frustrating ...
