Looking at screenshots provided on the store page, the game seems to use ripped content from other games, including but not limited to:

Overwatch (Tracer's pistol)

Path of Exile (one of the playable maps)

Other games also include Senran Kagura and Yandere simulator but the dev has removed any evidence of this, as well as removed the forum thread discussing the ripped content.

Update: The dev responded to my (admittedly childish) comments on the dev-log. I took a moment to write out the issues I had with his game in a forum post

If this guy is truly serious about making a genuine game out of it, I hope this gets him to improve the quality of it
