Hey, thanks a lot for giving my game a try! Collision and tiling issues are always unfortunate. Even though I try to pay close attention, one or two always seem to slip through. I've fixed them, so thanks for pointing them out!
Also, thanks for showing the different approach to combat. While it wasn't intended, the fact that the player can get through simply by spamming attacks is something I really wanted to avoid, yet it seems I inadvertently still made that possible because of the potent heal. I hadn't considered that, likely tunnel-vision. I'm going to take that with me and likely revisit the balance based on that.
