Pocket Gamer:

The latest update to developer HotGen’s Pocket Gamer Bronze Award-winning iPhone and iPad title To-Fu: The Trials of Chi has caused a bit of a stir.

[Despite] the update making the rock-solid platformer—and all of its in-app purchases—available for free, it introduces pesky ads that flash up at the bottom of your device’s screen as you play. This has upset some of the players that bought the title for 69p / 99c.

The iPad version is also affected, and that initially cost £1.99/$2.99. One recent review on the App Store states:

Now I always have an advert which I don’t usually mind but this time they actually affect the gameplay, it makes the game screen smaller, you can accidentally touch the advert and it is a bit distracting.

And that’s one of the more constructive of the recent slew of one-star reviews.

I find HotGen’s stance very odd, since it appears to show disrespect for those who already paid for To-Fu. If I’ve spent money on a game, the last thing I want is for the developer to suddenly make it free and shove adverts in my face. It also makes me concerned about other HotGen products. Will To-Fu 2 be next? What about Spacelings? (Note that I this morning asked for a comment from the company’s PR as to why this decision was made, and will update this article should I receive a reply.)

HotGen’s hardly alone. I’ve seen plenty of iOS games integrating house ads (sometimes in the form of ‘news announcements’), and I find such things irksome at best. But it’s pretty rare to see a paid-for title switch to free and have banners welded to it, compromising the experience for all and angering people who originally paid for it.
