Speaking of vertical scrolling shooters, I did get mightily distracted by a nice one called "Crisis Wing" over the new years summer break. I bought it for $5 during the Winter Steam sales. Best money I spent all summer! The game is well made and was clearly created as a bit of a tribute to the Toaplan shooters of the late 80s and early 90s. Games like Truxton, Truxton II and Grind Stormer come to mind. There's some fun modes like Boss Rush and Time Attack. Plus it has high score saving and achievements which make it a neat package. For those who are curious:

Good astro-fighting all!
