Congratulations on the solid submission and there were some really great concepts in here.
It took me 5 fish to afford any upgrades though as that meter was moving too quick for me apparently, but that's how it goes with an RNG-heavy game haha.
I didn't progress too far into it (1 of each upgrade) due to time constraints, but it was enough progression to get a feel for the basic gist, which I enjoyed. Not the biggest fan of 2D pixel art but it worked well here.
Thank you for submitting!
