I wanted to try this Irem shooter released one year after R-Type, and it seems pretty cool: very fast and with some neat and bold weapon designs. I not so sure about the speed control, though. The game is checkpointed, so playing it with infinite continues still poses a challenge. I beat the two first levels, it seems there are 5 levels which are repeated twice.
Completed stage 1/8.
Completed stage 3/8. I defeated the stage 3 boss by placing my ship right in front of it and slightly to the left, and just firing like crazy.
