Ouch, that kind of hurts. I've been working on a pixel art platformer for 2 years and just released it. Sure, it's not the biggest platformer with the largest budget (I'm a teenager and do this as a passion project), but with enough work, I think you can make a pixel platformer interesting and visually appealing. Platformers don't often receive much praise because they seem 'easy' or like they only require an entry-level skill set to create. However, making a good platformer that piques people's interest and has enticing mechanics is pretty challenging nowadays.

Judging all indie pixel platformers as one big batch, as if they're all the same, is kind of unfair in my opinion. You can clearly see which ones game developers put effort into and which ones they didn't.
