As many have pointed out the balloons are a bit....much, also, I feel like the price of upgrades (not to mention the sheer amount) makes the game take entirely too long and entirely too tedious. Sometimes I sit here 2 or 3 runs just to be able to BARELY afford 1 upgrade and it makes the game really boring. Also, at one point my game bugged to where it gave me an extra companion early after selecting one of my earned companions.
