Don't fall in the trap of the trolls, the wise thing to do is just read the
negative feedback and think if they have a good point, if they have a good
point, act in consequence, if not, ignore them.
Let me synthesize it in another way:
read(NegativeFeedback)
if (TheyHaveAPoint(NegativeFeedback)){
ActInConsequence(NegativeFeedback);
} elseif (! TheyHaveAPoint(NegativeFeedback)){
TryNotToGetAngry(NegativeFeedback);
Ignore(NegativeFeedback);
Don't everyone thinks that your project is "worthless", for instance, I've
read positive comments about it. If you feel bad you can try to "reread" the
positive ones to remember that there are people that likes your vision.
If some people thinks that providing only an iso is not enough, it should be
relatively easy to provide a tarball. But I have to add that calling
something "worthless" just because of that is stupid.
I personally think that the game is interesting and I love the level design,
specially the ones related to space :-)
Thank you for your game.
