It seems like a nice mixture of Enter the gungeon and Pixel dungeon.
There are some issues though
When I hold the cursor over the character, the sword flickers from side to side
It's really dark, even with 100 brightness. Maybe the light sources should emit more light over a larger area
Sometimes I lose track of where my character is in a battle. I don't have this problem in Enter the dungeon, which is a very similar game. The character should stand out more
There should be a map and an inventory
Other than that, it's really nice and I might buy the full version when it comes out. Are you going to publish on GOG?
