About this game

One scorching summer, the peaceful Earth transformed into a battlefield as the skies opened and sunlight poured in. Humanity, too weak to handle the new alien threat, saw its systems crumble, revealing the dark nature lurking within. To end the terror and control both aliens and humans, a new organization, X-Alien, launched a rocket to a hidden part of space beyond the moon.

They began experimenting on randomly selected children, injecting them with new superpowers to turn them into monstrous warriors for the space war. However, most of the children couldn’t withstand the experiments, leading to countless failures. Amid this chaos, the first success story, 'Ellen,' emerged.

Unlike the others, Ellen retained her sense of self during the experiments and devised a plan to escape the lab. During her escape attempt, she couldn’t leave behind the young test subject who had helped her, so she ran back through the long corridors.

Facing off against robots and researchers, Ellen fought with all her might, praying for a tomorrow where she could choose her own path in the war and where hope could return to the world. Help Ellen escape!

Typical Rougelike type of game, some of the power-ups are good, some not so good and it can hurt a run (update: the faulty power-up has been removed) where as the right upgrades can make a very good run. Some expected difficulty spikes but it's accessible enough for f2p and I've not found myself blocked from progressing. Ads after each run, however, you can skip them in a few seconds so I don't mind that.

the game does feel low quality at times, but it's overall pretty fun. sadly, you can tell it's another mass-produced game, which really sucks because the character design and dialogue has a lot of charm. but overall it's still a very fun game

I would like to like the game. But the game is really not that refined. English was not the default language when i started the game. At the very least, make it so u can pick it at the start. The movement unfortunately have that either u go 1 or 0. Cant micro control my movement speed to dodge bullets. Lastly. The game got hard stuck on one of the game's package ad. When u try to close the ad, the game gets stuck.
