Have you seen the sheer amount of the comments? Of course they won't read them all, they're still an indie studio and they don't have work hours to waste on reading suggestions. Also I'm pretty sure they already know what is good or bad for the game, so there's no need for like hundreds different suggestions every day
I Agree with you but I feel like it's important to get the message across nevertheless. There are comments with constructive feedback among those suggestions, so maybe they look for a thing or two, even though they already know where the game is going to go. That's what indie devs excel on after all, they listen to their players way more than the other companies on the market.
