This is one of my favorite games of all time, and the most recent updates have only increased my adoration for it. However, I have 1 issue: the controls.
I've been playing this game since 0.0.3, so I've gotten used to picking up weapons by left-clicking. Now, however, I have to press "E" to do it. This probably won't be an issue for new players. But what MAY be an issue for new players is the fact that "E" is also how you interact with NPCs, portals, and fountains. It's likely that someone will find an ultra-powered Ordinary Pineapple sitting next to a Juice Portal, try grabbing it, and get teleported across the map instead.
And since "Tab" opens the inventory in some other games, I keep accidentally hitting it instead of the actual inventory key. But that's my own fault, so... yeah.
If it's possible, I'd like an option for players to bind keys themselves. If it isn't, then... well, I can probably get used to the controls.
P.S. I also think it'd be funny if you could shoot the Pizza with the Pineapple, resulting in it exploding violently and damaging everything within a certain radius. This is based on the real-life phenomenon of putting pineapple on pizza, which (as we all know) creates an abomination that's harmful to all life it touches.
(The pineapple thing's mostly just a joke suggestion, by the way.)
