About ULTRAFUN

ULTRAFUN is a game about patience, rewards, and goals.

...

Take care of the last remaining fragment of Planet Ky, a world obliterated long ago by the Greater Void lying within.

The Kyzt, in a last-ditch effort to tether itself to our world, formed into one Kyztling:

... Qubert.

A renowned scientist, you must help Qubert to restore the ecological balance of Planet Ky, and to eventually reconnect your species with the Intergalactic Federation.

Relax. You've got this. This is all you have to do:
  • Feed your scientists some delicious and ethically-sourced Voidling cuisine!
  • \Channel your progress into the psychic relay, a natural and vaguely tree-like organism growing within the Ky Fragment.
  • \Make friends with your Kyztlings. To be clear, this is not a multiplayer game. I am talking about virtual friends.
  • Realize that this game challenges you beyond the limits of any lesser game. Are you gamer enough to attain GAMER VALHALLA?.

That's right.

If you download & play this game, I will personally send you to GAMER VALHALLA. I'm the developer and I am allowed to send you there. Buckle up, because you're going to be sent there at an extremely high velocity. Wear a helmet.

I have absolutely 0 idea what i'm doing but i did something good. this weird little game is strange but enjoyable. I found myself saying "what is this game??" so many times it. there is some lore in it that i have no idea about but i think i'm getting somewhere? this game is worth the run-through and it is free so I'd say to give it a shot. don't expect to understand anything though

8.5/10 I still don't know what the point of this game was but it was really fun. Perhaps ultra fun

Really fun game. maybe some upgrades (really expensive) for the weapons(faster shooting speed or more ammo capacity). Keep on doing what you're doing 9/10 A tutorial or guide could be good

"ULTRAFUN" is a weird hybrid game... and as always, novel ideas are not always good ideas. What do you do in the game? This hybrid game is a bit of a Vampire Survivors ripoff autobattler but backended by a rather poorly done management/sim/builder/RPG... thing. The problem is that none of the backend has much impact on the front end, and neither the back end or the front end are even implemented remotely well enough that anyone would take them seriously as a game. This features really godawful pixelcrap "art" instead of real graphics. It's hard to say if this was because the developer didn't have the skill to do the job of creating 3D visuals, or couldn't afford to hire someone who does, but it also doesn't matter. What matters is that this looks much worse than most other games because of that decision, and that's a major deterrent to gamers. Games like Terraria and Stardew Valley succeeded [i]despite[/i] the bad graphics, not because of them. Now on to pricing and value for gamers. This is "free" enough (not every "free" game in the "free" section is truly free, there's usually some hidden price tag), at least you won't be expected to spend any more money after you down…

Boltgun 2 price: buy the sequel, or the cheap first game?

The Boltgun 2 price has no cheaper route on launch day — our record shows one listing, unmoved since September. The first game is the bargain, but a smaller one than it was.

Rust price: why the cheap keys vanished, and when to buy

The Rust price has two answers: an official one that barely moves, and a reseller one that sat in single digits for 95 days and then disappeared. Our record shows both.

Planet Zoo 2 price: which edition, and when it gets cheaper

Planet Zoo 2 is out today. The Planet Zoo 2 price splits two ways, the cheap pre-order keys stopped existing three weeks ago, and the original got dearer as the sequel landed.
