I fondly remember playing through this a time or two way back...so this was my first download.
The graphics were good at the time (they still look good), the music is catchy, and the 'slowdown' in various places actually adds to the charm of days gone by.
But as many already know, and a few will find out, this is old school HARD!...so prepare your mind for a bit of side scrolling frustration and memorization. From the beginning, the hit detection is totally unforgiving and if you don't cuss now, you will. Oh..You will...
In other words...I love it!
