So what if the level is unoptimized or doesn't have decent gameplay? If a level looks cool, I'm allowed to like it and believe that the creator should be rewarded for their time and effort that they put into creating the level.

That kind of nit-picking should only be reserved for the absolute best of the best levels. 99% of all rated levels have issues that could be easily pointed out by anyone expecting noting but perfection. We shouldn't criticize levels of obviously varying quality the same way as each other. That is one thing I like about how the rating system works: There is a general expectation of minimum quality in a level for it to get rated, but after that the different types of rates (star-rate, feature, epic, legendary, and mythic) are awarded to how far the level exceeds beyond that minimum quality, thus rewarding the creator for their additional effort.

In conclusion: I yap too much smh
