The current public Version V0.0.6 is a bit too hard. With the coming updates difficulty adjustments are being made.
Well, It is possible to beat, so it is a matter of perspective.
also saying, "you should" do this and that as ending, on a free game in development is redundant. This won't be the end of the game, so creating an ending makes no sense.
Feel free to wait until the game is finished and got the final balance ;)
As someone who has been here since version 0.0.1 the game has changed quite a bit, expecting an indie game on version 0.0.6 to have a fully fleshed out game end when it still hasn't had other parts completed is just insane. To me it sounds like you just want to complain to complain. The only version of this I wasn't able to beat was version 0.0.3 and that was just because of my own lack in skill.
