'it was much nicer than it deserves' is in itself quite a charged thing to say! Criticizing a game does not require demeaning the creator.
Your original comment on the game—though the exact words you chose may be a bit harsh—is not something I entirely disagree with.
You should understand, though, that there is no entitlement on your part to a complete game! You've chosen to play a game made for Ludum Dare, which in itself should come with the knowledge you won't be playing a complete product.
Though it wasn't the clearest in the game, I realized that this was likely a game with no set ending, so I just spent about as much time on it as I felt like I needed to to get the gist of it. As much as I wish there was more, this is far from a valid target to call 'barely a game'
