Should've been a free demo, tbh. Charging money for this is a massive red flag.

agreed. no way im paying $30 for this. maybe theyll reduce the price with all the feedback

It'd be dumb as hell for them to try to sell the game for a price befitting the game you get right now. Which would be approximately $0 except maybe, maybe the PvP. (I have not tried the PvP.) Buying now is pre-ordering the game it's going to be. If you wouldn't do that (which is totally reasonable) you shouldn't buy this, and you should know that.

It would also be a blatant betrayal of the kickstarter backers who paid $30 for it.

a bit steep no

They cant charge that, what happens if their entire audience buy the game now lol have to set a reasonable price, you're still buying the "full version". Im a +1 for demoing at this stage though, what they have is prettey demo worthy current, would provide them the input they need on the MP/balance side of things and help alot of people decide on buying and supporting its development. Ill buy it at somepoint! Would love to try it out and do a few 1v1's in the meantime though.. (Dev's, Send me a key and ill do some 1v1 then actually buy it once chritmas is out of the way, pinky promise!)
