I'm a little concerned about the way that this game is currently advertised on Steam. From the "About the Game" description you would think that you would be getting a game much like AVWW, albeit improved and expanded on, when really the game is nothing like the first one. Indeed, it is really closer to being a spiritual successor than a proper sequel.
"A complete re-imagining that takes the best ideas from the first game and takes them to the next level."
This sentence, particularly, starts well but is very vague in how the game is re-imagined, it even seems a little contradictory towards the end -- can a re-imagined game just take some ideas from the original and "take them to the next level"? The fact that this game has a completely different old school 16-Bit era Metroidvanian feel is not apparent at all from the advertising.
This is bad in two ways. One, it is giving a slightly false impression of what to expect from the sequel to anyone familiar with the first game, and two, it is not particularly enticing to those fans of old-school 16-Bit shooter/platformers that might actually be interested in buying this game.
I propose some rewriting of this blurb to emphasize the fact that this is an old school metroidvanian shooter (and very different from the first game). Doing so should also help mitigate the damage caused by those expecting to be able to use mouse control; after all, who really expects a 16 bit era style metroidvanian title to be controllable with a mouse?
