Hey there!
The movement and speed felt great, but smoother turning would be even better. There's a bug where holding a movement key grants super speed! I loved finding the different weapons with fantastic art, but some combat feedback like hit effects would be nice. Getting lost was a big issue for me since the similar-looking tiles made it hard to remember where I'd been. Maybe a mini-map could help? Overall, these are just some suggestions, and I enjoyed playing!
