No joke this is the game that gave me Chrometophobia.
I remember wanting to speedrun the campaign with the Dragon, but i didn't want to grind for upgrades so i took a loan, it worked like a charm so i figured "Hey why not take another loan" and i think you can see where this is going... The rent went up so much that it was eventually impossible to pay back the loan even if i won first place in every match, that didn't stop my creditor from demanding that i pay him back every round, i started to lose more and more matches due to stress, and i couldn't buy any new upgrades because of that and the game just kept on getting harder, which only made me freak out even more, eventually my creditor came and took all my upgrades, leaving me with the worst dragon at the hardest part of the game, and i have never taken a loan in my life ever since then. xD
