Lots of bugs that should have been caught with a single round of playtesting. Food spawn makes food spawn slower instead of faster, both the improve food and price reduction bonuses go away after upgrading food, the prestige tracker doesn't display the correct number, prestige scaling is terrible, the fourth prestige costs more than it would take to beat the game, and the final food is functionally useless, it takes so long to spawn that there's no reason to put points into it instead of the fourth one. Also you spelled price wrong. The artwork is cute and the idea is good, but you really need to play through the game before posting it to check for bugs.
