This was a kick in the nostalgia!
Notes:
* I really enjoyed the ruins.
* The exterior needs some additional polish. You can get very far into either side of the river and the water texture will disappear. There was also a corner of water texture that was slightly above the river itself.
* The ledge grab was a bit nerve-wracking. I kept feeling like I wasn't going to catch the ledges. There were several times where I shouldn't have been able to make the jump, but it automatically grabbed the ledge anyway. Maybe increase the height of the jump by a tiny amount to fix the gap issue might work.
* I really wanted a "hello," or something similar from the bird robot. Having an extra screen to click through would be annoying, but maybe some text as you hover above each option would give it more flavor.
