Very fun game to walk around it. The movement felt nice with that scraping sound. Great atmosphere and good sound design. One of the better /agdg/ - frog games.
The UI doesn't clearly show what you're selecting (it's only slightly darker).
No music for the opening and most of the game feels weird, but I guess that it's part of the atmosphere.
Some z-layer issue with the first interactable object, the frog moved under the purple indicator.
Jittery sound and movement when walking into walls. Some jittering when moving around, unclear whether framerate or just Unity issues.
No menu? What does strength do, where can I see the current strength? What does bash do? What skills will I have in combat? How can I save?
You probably should add a prompt or tutorial when picking up the first block, since most players refuse to read.
Early combat (or all combat in the non-DD level) is very bland - just slowly bashing - and might turn players off early (during the refund period if you'll publish on Steam) so be careful with that.
