First before I get on to some details, I LOVED this game! the concept was a good one, amazingly executed! The art and animations are really good. The music, i men its really good! Progression this game is a bit slow but its great! The featur to allow you to progress to a new dungeon risking your loot, or leave the dungeon and secure your loot is also a great mechanic. The shops are also good, especially selling items.

But there are some complaints.
First of all the combat is a bit finicky, its hard to aim your sword.
Second when the enemies teleport in, it occurs when the player is SUPER close, thus almost guaranteeing you need to buy another heart.
Third, if enemies get too close to you when you are swinging your sword, you get damaged, if there was some way to prevent that, the games quality would greatly increase.
Fourth, the amount of money you lose is INSANE!! Lowering the percentage of money lost would definitely make it more beatable.

Otherwise, This game is great! Make more games because I'll look forward to them.
If you do plan to update this, PLEASE DO!!! Its a great game and worth updating more.
