I mean...for that price (€2,78) it's probably ok, but...that's something, I'd rather play on my mobile (if at all).
Also: If you wouldn't write it in the post, I wouldn't know that the game's supposed to be called "Fill Fill"...that "title font" is as ridiculous as that from certain Black and Death metal bands.

Game That Kind of Looks Like the Mini-games That Pretend To Be Hacking In Some Other Games: The Game

Oh, lol. They tried to spell "Fill Fill" with pipes. I didn't recognize that at all.
Instead I thought they had branching pipes implemented as a game mechanic. But no, they haven't. It's only end-to-end connections.

I have a similar game on my mobile phone. Kinda nice while you wait at a bus stop. But nothing more.

Even knowing what the title is I read FU FU. Rude.

Ah! Yet another attempt to monetize a free browser game. Search for "mindgames fill fill" you get to the ad-sponsored free version, if you want to try a "demo" before spending money.
