Relax. Ignore the people saying the gross things, and just focus on what you can do without getting burnt out or whatnot.
Everyone is gonna say "aw but I want it nowwww" but nobody's gonna get anything if you're not given the time to do it properly.
Do not worry about if you can "do it better" or anything like that - game development is a process, not a one-and-done deal.
This sort of thing takes time, freaking out and panicking will only result in it taking longer.
You've already proven that you're doing what you can when you can. Anybody that's whining about it needs to boot up Godot and try making even the most basic game for themselves - that shit ain't easy, hence why it takes years for even seemingly "simple" stuff to come out.
