Wow! Thank you so much, I suppose it took you a good couple minutes to write this, which makes me impressed. You made the points well explained and clear :) I knew about couple of them very well, but some gives me more to think of :D
I'll try address some issues you mentioned :)
1. Talking about endgame; yes... it's bad, or it doesn't even exist. At all time making this game I was certain that anyone will last playing max 5 minutes, and won't (as it turned out after releasing it) beat my own highscores :D So I admit, the endgame exists ONLY when you lose, there's nothing else prepared.
2. The 'fishing bank' you mentioned is probably very confusing and especially when your income is eg. -10 fish, many people are confused if they're doing good or not. Getting rid of the fishing bank completely is probably the best idea I haven't thought of, or I thought this will be the highscore?
3. Drag and drop being how it is and pieces spawning on the map not outside - all I can say, is that was my first game jam, and as always I probably have focused more on the game's look :)
Once again big thanks! As you said, I'm probably not going to update it, but your criticism might have given me a better understanding from a player's perspective :)
