As I've waited for other indie games I'm looking forward to, I've decided Playtonic's communication isn't too bad. Shovel Knight, for example, has had very little news about its newest campaign. The fact that Platyonic didn't announce anything super cool on the game's anniversary suggests to me that they have big plans for a future announcement: basically they could either show us the 50% of stuff they really want to right now, or show us 100% of the stuff they want to with just a little extra time.
I guess part of my optimism comes because of how communication with the Switch release was dealt with: they kept almost completely silent on the issue until they could say "BTW it launches in a month!" which I was certainly not expecting. I'm left with this idea that when they do announce stuff, it'll be like Christmas.
