I agree that the S key is very deadly :D definitely an action that I wasn't used to lol. I think the combat mechanic is very neat, and it opens up some interesting choices regarding upgrading 1 item of balancing upgrades across all 3. The game does seem to ramp up in difficulty rather quickly, where if you're unlucky you can get hit for a lot of damage before being able to strike back. I didn't manage to make it to the end but I did enjoy the attempts I made :D good job!
