Fun game, cute story! Liked the graphics and sound and it had a good GameBoy feel. The tutorial/intro could use a little more clarity, since it wasn't immediately clear when the shop and other things were open and how the game was meant to be played.
The first time we played it, we put the odds of fishing at 1% (to potentially hit it sooner). What we did not realize was that fishing was a minigame! I thought it was just a cutscene, and was sad to never hit it in the 96 tries. Then in town, we learned there was a shop and recycling... but we never got any trash.
We then did a new run, actually catching and selling trash. We bought 3 clovers (extra luck) and figured it would be okay to give some away... and doing to completely removed the benefit of a clover and (seemingly) brought it back down to 10%. At the dock it's clear it still applies but the fish did not say so. It DOES seem to have removed the extra luck the mirror gave though, which combined made it pretty demotivating.
