1] Should the fishing system be a permanent part of MD? If so, would additional games add more to MD or just distract from what MD is all about?
Yes I think it should be permanent part of the astral plane. It is great for killing boredom but also training your mind and your reflexes. Anyway it was fun game and i really enjoyed it.
2] How was the progression of upgrading the poles/lures with regards to catching fish and earning pennies? (Was there anywhere which seemed to take particularly long or was very easy?)
At the beginning little hard but better as we earned more and more pennies. Haven't tried many combination with the poles and the lures but it was not that hard to catch a fish.
3] Do you have any suggestions for how to improve the fishing system?
Faster overflowing? . Just kidding. That part was fun. Maybe you can add few more free items laying around the astral plane that will improve our fishing experience. Maybe you can add an option so we can make our own pole and our own lure with some of the random items.
4] Should there be more items / fish / extras included? If so what should be added and what would it do?
No I think there is plenty just as it is right now. Maybe few extra baits(MD related ) can be nice.
5] Overall what was your impression of this quest?
Well I never liked minesweeper before and never actually played it. It was same with the fishing at first, but when I did my first upgrading of the equipment it was getting only better and better and i got really hooked up on it. The idea with the overflowing was great
