I liked your game, especially that you have progression and interesting combat system. Graphics was a little bit dark, it was hard to see anything on the second level, but I've managed. Music was probably a little bit too quiet, but it was there and added ambience and atmosphere.
What I discovered that you really need to have a block at the start. Basically random progression made it quite random... I mean some runs are just destined to fail because you didn't get moves and even if you're doing everything right, you'll not be able to finish the game because of it. Maybe adding "pick one upgrade out of three" progression can fix it?
Other than that, once I've understood how combat works and once I got proper moves it plays really fine, maybe a bit on a slowish side once you start to defeat your enemies without loosing any health. But overall I can see how I can sink in several hours in that kind of game if it becomes a little bit less random.
