Your Nessie is cute. The artwork in general is nice. This is a good start for a learning project. Looking over your devlogs, you've made great progress.
I hope the below doesn't come across too critical. These are just some things I noticed.
After clicking to play the instrument in the yurt I walked away and then was not able to interact with anything else. I had to refresh the page.
After clicking to sit on the log I tried to click again to get off, but no matter where I clicked it kept sitting back on the log. I also tried using WASD to move. After a bit the character got off the log, but I was treating it like the lights as something you toggle. I'm not sure how best to convey that it is a preset animation, rather than click to sit and click to get up. One option would be to disable/ignore the input while the animation is running so it doesn't restart with each click.
It might help if you required the player to click on the object to trigger it, instead of clicking anywhere on the screen. You can have a generously large area be clickable. I just think it would be nicer if you clicked on the object, as clicking in different areas causing me to get back on the log seemed a bit odd to me.
When the exclamation mark appears above the frog's head, I clicked again, which restarted the fishing. It made me think it was an interactive event and you had to click quickly enough when it appeared to catch a fish. After seeing the animation restarting I acknowledged it was just an animation, like with the log.
When first bringing up the Pause screen it looks like the volume slider is set to 0/the bottom. Clicking anywhere but the top lowers the volume, when it looks like it should be raising it.
For web, pressing escape exits fullscreen, so it is good to have an alternative input option, such as P, to pause.
Overall, this is looking nice. Keep up the good work.
