Great game with beautiful art. I played the complete thing (v0.3). The warehouse keeper was a tough mofo.
Things that could be improved:
1. Sound bug: When I change the sound volume in the settings every second step (2, 4, 6...) is super loud for some reason.
2. Sounds that occur in the middle (like sword slashes) sometimes come from the left or the right. I think that should only be the case for sounds that clearly originate from the side (left or right third of the screen).
3. The blood(like) effects need to be reworked. The particles sliding on the floor look weird.
4. The symbols of the masks are a too abstract and don't look at all like the thing that they do (protection bubble, slash). It should be easier to recognize.
5. The player movement animations look a bit stiff and the mechanics could also be smoother. But don't ask me for details, it's just a feeling.
6. Windows thinks your exe is sus.
But really great work overall.
