I think this game is really well thought out and put together. The art and animations are very good and the main character's design is great. The axe throwing mechanic is very unique and there is a good variety of enemies.
The UI obscures a huge portion of the screen, making it hard to see to the left. The controls are also pretty janky in my opinion. Pressing, holding, and releasing space bar to jump at different heights really messes with the fast tempo set by the character's high move speed. Pressing E and R to attack is also quite difficult when running to the right.
For me, one of the most important aspects of a game is how good/fluid it feels to play. I think the concept of a drunken berserker breaking out of a dungeon with a magic axe has a lot of potential for a very fun metroidvania game.
