Alright, this bit of feedback will be sequential, so this should be smooth commentary.
First off, I like the graphics of this game, the animations could use a bit of work, but I believe in you. The music however is fits perfectly. One thing I realized is that there is a strange red square in front of the character after you attack, It looks strange.
I don't really like that I have to click to do all the actions, but contol my character with the arrow keys. I mean opening doors and using a sundial. It's not very user friendly I suppose, you should try changing the controls to allow click movement, or switch movement from the Arrow Keys to WASD. I honestly have no clue where my health is displayed, so I died in the first section of the demo.
I replayed, unlocked the Key, and now I'm moving on. I hope this is simply a tutorial section, because I'd much rather find a Key than kill monsters until I can summon one. The combat is a bit clunky, once you begin combat, there's a feeling of being stuck for a while if you try to back up. So, the pace of a dungeon crawler is kind of removed because approaching an enemy is a sure attack to your HP, meaning that you can't really run in poke and back up to fight more cautiously.
I was also wondering if you could Loot Skeletal Remains, if not, I don't think hovering over them should tell you what they are. I really liked the Old Journal bit, hearing the note read aloud was awesome, I hope there are many more of those type of things.
Not knowing how much health I have is getting very annoying.
I just rage quit.
How do I gain more HP, I saved at a point I kept dying (after I kill the ghost and have to fight a spider a second later, and keep dying. I tried eating food, still died just as fast) Is there a healing potion I'm missing, because not only have I no clue of my HP, bit I don't even know how to keep it up.
