Even without playing it, I'll be giving it a good rating because I kind of have been in your position.
Making powerpoint games can be fun or kind of stupid, depending on how you want to make the game, but in the end, the entertainment value is what matters.
(Side note: Please do check out "The ShopKeeper's Secret" made by yours truly, and rate it if you were entertained at the very least. This is a shameless promotion so you can choose to ignore this part.)
If this does get high points from the judges, I congratulate you. Your work has been appreciated.
Well, whatever happens, I wish you the best of luck.
