Played for a while, put some fire out, after the first 2 fires the newly spawned fires did not move towards the home.
The gliding feels nice. You're hard to steer properly while gliding, banking is better than just turning but it's still slow, the best turning method I found was to stop gliding to reset my horizontal speed and then glide again. It works fine I guess, but I'd prefer if you were more maneuverable.
Climbing feels disorienting because of the first person camera.
There should be a sound cue for picking up water bombs and some indication that you've got one ready.
As a movement demo it's fine but I don't think putting out fires is a particularly compelling concept. Might work better as a pure traversal game?
I'll play more of it if you continue working on it.
