I thought the level design was quite good for a game this simple. It's very open but I always felt like I was going the right way. I could easily see what was up ahead and it twists and turns in just the right way that I see what I'm looking for or where I've been in time to know where to go. Levelling mechanics in games of this scope usually feel redundant. But in this, particularly because levelling up heals you, felt critical and integrated with the game. The stats increase was just the required steady progression. I like that it made me fight more enemies to heal rather than running away from the fun.
That being said, the fighting mechanic is a bit simple, and it's hard to aim in the correct direction while moving, so most battles were fought one-on-one and along a cardinal direction. Because of this, there was little skill expression and it got repetitive quickly. That being said, I played it through to the end and enjoyed the tid-bits about the story.
I did feel the ending was quite anti-climatic, I wish you'd mixed it up a bit and made them tankier (it was over so quick), and done something to make them not just a normal enemy. Like make them slower but maybe unable to be stunned by attacks to make it feel more dangerous but still fair.
Some really good elements overall, and I hope you make more. But visuals, audio and theme integration weren't particularly strong so that will harm the score a bit. Thanks for making this game!
