I love the presentation on this, it's very gameboy-esque and very spooky and looks great, the effects with lighting and changing palettes are super impressive!
I don't love the movement, even small jumps hit the ground so ponderously and it doesn't feel good to move around. It seemed like there was a glitch when I get hit while in bat form and then quickly turn into a bat again - like the old timer from the first time I turned into a bat was still running, the power wore off much quicker the second time.
This looks and sounds great and I love that it's a complete game with a clear goal, very fun to play, well done!
