So, this game has been getting a few updates as of late (most recent of which has added a new level). Are we ever going to get these updates for the GoG version? It really does need some fixes still (AI bugs, secret level broken, game-breaking bugs) and it seems unfair that I can't get them just because I wanted to buy the game from a retailer I already use and trust.

I too am concerned about this. I realize the content is new at this point, and maybe it just hasn't been implemented, but I wanted to lend my voice and say I'm waiting for this content too.

I emailed the dev about this, and they just sent me a pre-written response directing me to their FAQ. Not sure who else to contact about this.
