Bad balance that ruins the game

Good game, but some problems ruins it:
- No possible upgrades on first levels due to lack of money.
- Food upkeep near impossible to satisfy when >500, forced to buy food.
- Far too easy in normal levels.
- Talents price way too expensive regarding the income.
- Boss too hards, in particular lvl 100 which may be impossible to defeat with some talents trees.
- Bosses lightning ball is a shame: blocks all attacks, stay too much time on screen and have a too big radius.

Game balance must be corrected. Until then, only one star.
