I didn't make it very far into the game, but I found the mechanics fun to get used to. It took me a little while to get used to the idea of the dash being an attack, but I realized you could just walk towards your attack and you'd basically stay in place just fine.
Difficulty is the kind I enjoy, although perhaps a health managing system would be able to mitigate that feeling of unfairness some might feel. Otherwise I think it's a great game. And although presentation isn't great I like the "Thomas was Alone" feel of it. Proves it's a good base.
