Haven't played a classic arcade space shooter like this in a while! I enjoyed it, although it was pretty tough and I could only make it to level 4 or so. Ship control felt energetic, but a bit fast for me to feel like I was truly in control. Destructible terrain was really awesome, and the classic scoreboard at the end was a nice touch. The rewind was hard to predict, so I didn't find it that useful -- but I can imagine how it really would be valuable for survival if there was some way to know where it would put you, like a visible echo. Nice work!
