We've announced Time Recoil officially today! It's a brand new game we're working on. We hope to start beta testing during April on Steam - we'll see if we can achieve that!
In Time Recoil the player is given a super power: Kill to slow time. Killing will trigger a slow motion effect, and killing additional enemies while in slow motion charges a special move. The more the player kills, the more powerful the special move becomes, starting from a simple dash and ending with a mind blowing psy-weapon.
