Liked the gameplay, but could use some kind of score counter. Time warp mechanic was interesting but no clue if you can decide when to warp or is it time based? I would prefer personally to make it input based not time based when I warp after creating the "warp zone".
Sound was okay, shooting noises could have used some work but music was nice.
Liked the graphics idea, wish the walls were more worked on and that there was more of variety when it comes to enemies ships.
Didn't manage to beat the final boss. But all in all solid entry.
