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.

it wont let me properly start the game, and when i try, it lags my phone to the point that even pressing the power button takes like 3 minutes to respond. meanwhile once the screen finally loads it looks like a corruption of text on the screen, atleast the icon in the bottom left and the dialog boxes show up, i guess

love the gameplay and the art style. there is one bug that ruins the experience for me, and that's when I get the shield upgrade for the claws. the audio no only overlaps, it remains even after the mission ends.
