We could make new backpack items such as a potion that is very rare but it boosts the luck of getting rarer bro Mon by a tiny bit. There could be a VERY small chance to get a potion after catching a bro Mon. There should really be a way to save your progress, for example once I was playing Bro Mon and the next day all my bro mons and potions were gone, so it would really help. 
Can we add a cool feature like a index that tells you all the Bro mons stats and tells you Which bro mons you have. there could be shiny bro Mon and a shiny index. thx anyone who is reading and pls vote.

This would be very hard to code though, so it wouldnt exist for a while
doesnt this already exist
