Cool game! I think that the mechanic where you always need to equip/unequip your weapon is a little bit frustrating: you go to the boss room and you don't understand why you can`t do anything, because your weapon unequips automatically. When you want to activate a save point, you also need to unequip your weapon.
Most of all, I liked the teleportation mechanic. It is really good and fun, and it opens up a lot of space for attacks and other actions.
I also had problems with the parry: until I changed the keybindings in the settings (I changed Shift to Ctrl), I couldn`t do a parry.
Overall, I had fun playing your game. You did a great job!
