This was a fun little game! I managed to get Grandmaster on my first go through, though I am curious if the fox would have done anything if I hadn't - either way, I was happy to feed him ;3
Aside from the one major thing which I assume was due to a lack of time (no tutorial for the concentration mechanic. Thank you for having one on the page here!), one thing that jumped out at me as something that would help, is a sound cue when more thoughts emerge during this part. I almost missed the second onslaught of thoughts because I looked away while waiting for the timer to run out. A sound as they fade in might be nice.
I really enjoyed the art and the resource management system! And the tone was most certainly cozy heh Congrats on finishing the game in time for the jam, and if you polish it up - I wish the whole team the best!
(in browser, the game didn't run great on firefox, but I didn't have any issues on chrome.)
