cheaper in groupbuy

If I had to guess I'd say they make most of their profits from the store section of their page these days, or at least they seem to promote those sales more heavily than the bundles.

IMO the real problem was that they pretty much stopped selling anything else :x

To be fair, Indiegala bundles have always tended to be dog shit. Flash type games, poorly optimized. What you could see in create your game in 6 hours tournaments.

And the few that have decent games have expensive prices.

I don't know if there are more and more +18 packages, but I suppose they sell enough to raffle and inflate game numbers in the accounts. (I buy them for the second one, I think they are 12 games for 1 dollar and they may have trading cards in the future) (I'm not interested in games, I'm gay xD), but in my opinion they are bad games even to spend some time +18 .

They doomed themselves with the whole happy hour gimmick, so devs/pubs haven't wanted to be in their bundles for years. Same reason Groupees died. Only a few people regularly buy their bundles and it's mostly people that buy bundles in large batches during happy hour for group buys.
