There really should be a way to review without rating. I am giving 5 stars on the basis of my trust that this game is likely on-par with your other work, which is all 5 star stuff.
But the reason we really need a way to review without giving a rating is in the cases where players can't get your game working. I've noticed one other review with a similar, though not identical, problem.
Namely, what happens is -- the loading screen works and you can smash the 100 slimes for that medal. Then, once I click on "Play", the initializing thing very very briefly is at the upper-left and then the plugin crashes. This happens 100% of the time for me, or at least every time I reloaded the page and tried again.
To date, this is the only one of your games I've ever had any problem getting to work.
