Hey, love the mod, but I feel like it could be better.
First off, a bug report - cancelling the minigame with ESC, then fishing the same puddle results in new fish being spawned, but the old ones are not being despawned - so 2nd time you have twice the amount of fish, 3rd time you have 3 times, etc.
Also the marlin is too hard to reach, it spawns too deep. It should be slightly higher up, and maybe have a rare variant of its own?
It could also be cool to give normal fish a chance to give extra loot, like their rare counterparts, if you fished them deep enough - the chance scales with depth, starting at 0% for the surface and going up to 50% at 5000 depth?

Oh, thats a shame - loving your mods!

Ugh my image editing software didn't save properly twice over and I lost the new fish I added. Going to do this right some other time. Probably doesn't work right now.
