The graphics are great, I love the style. And the grid movement is ok but I got off grid more than once and couldn't enter a door. Combat is better served fleeing as you can die even to a single enemy from full health. I would almost suggest to not even include a web build if it's not at parity with the download. Sound and music would have gone a long way as I didn't download the game. Also the dialogue should be skippable, after dying twice it was a slog to sit through it again since the game restarts you.
Unfortunately I couldn't finish the handful of times I tried due to getting off grid and I believe I needed to enter that particular door to advance..
