Dang, this game feels like a full release!
I really really enjoyed your art direction. The layered backgrounds work very well to help convey a living world. The fuzzy effect on the edges is also a nice aesthetic choice, and I really like the bits of atmosphere/glow some of the grassy objects seem to emit. It's a very pleasing aesthetic and meshes well with your pixel style
The timeslow ability is SO neat and really well designed and executed! Its duration is very well-telegraphed to the player and it's very intuitive to use.
The first bossfight took me a bit to understand I could reflect projectiles at them, but once I realized your intent, it was a fun challenge to precisely reflect it at the right time.
The menus are clean and read very well, there was never any confusion as to what you were trying to show me on-screen.
Seriously, really really great job on this!
