the only problems i had were a lack of sound/music, and that the betting function needs a rehaul. it seemed to pretty consistently lose more often the more i spent on improving the odds, and it didnt make sense that i had to bet 100% of my money instead of choosing the amount. (same with the stocks - it's hard to actually play the market when you can only really invest in one or two at a time)
also - the heroic tangerines are a hugeeeee mistake to buy - they actually made me lose tangerines per second despite being the 2nd most expensive unit in the game... why??? if you're going to add that kind of dynamic to the game, you should really let the player know, especially when there's such a huge wait between the mutants and the 5d tangerine. it's frustrating to invest a lot of time into buying a bunch of the heroic ones, only to realize it's just taking you further and further away from your goal
