Wow. Thanks for the incredible feedback. I absolutely appreciate it. I'm gonna reply to all your points!
For sure it needs more time. 4 days was barely enough, but I'm super excited about everyone's responses and I'm coming around to the idea of making this my next project. So this information is critical.
As far as the random selection, you're completely right - if I had time I would have switched the inputs, but it was getting down to the wire. The random selection was pass 1, by the time I had the minesweeper mechanic down I realized just picking the one you want would be much simpler and easier.
As for the puzzle example you gave, that's the kind of thing I could only shake out with playtesting, and probably some fancy algorithm to verify one solution for each puzzle. Of course I'd also like to have difficulty ramps. Start with less colors and fewer tiles, etc.
QOL things like volume, making the animals chill, all good suggestions, all totally would be in an options screen.
So thanks so much for all this info. I'm cataloguing it and its real likely I'll be digging into a full release after the jam :D
