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!

Love the game! Pros: -Music is catchy. -Nice graphics -Main character is "cute" in her own way, 🤣. -Skills (mutations) are plentiful and actually make a difference. Cons: -Way too many extra items that I won't use. Maybe have a buy back system to gain money or gems. -Game is a little on the easy side. Maybe have a Hard stage mode. -Cant change my name. Maybe have a personalized system for that and the main character. Keep up the great work dev team!

Just WOW...out of all apps I had issues with. This one takes the game. From the get-go when starting the game. It started malfunction to the point my phone went completely haywire. I couldn't get anything to work on my phone and the game would not shut off in the background. Once I got back control of my phone I immediately uninstalled. I'm not sure if this app can do any damage to your phone. However I would be weary of installing it. Hopefully they get the bugs ironed out sometime soon.

Typical Rougelike type of game, some of the power ups are good, some not so good and it can ruin a run(the power up that has a flying drone circling around you doesnt seem to work),where as the right upgrades can make a very good run. Some expected difficulty spikes but seems accessible enough for f2p. Ads after each run, however, you can skip them in a few seconds so I didn't mind that.
