Okay, this was a pretty okay short game, and a pretty nice little Ludum Dare entry overall.
The minimalistic, retro presentation is okay, nostalgic, and it works well for the theme's concept as well, since most games back in the Atari era only consisted of a single screen.
The gameplay is pretty simple, you basically jump around, avoiding enemies and spikes, and shooting blocks and things that can get in your way, in order to grab a token in each stage and reach the exit carrying that token. When you die or leave a stage, you get sent to another randomly selected stage, all of which contain a token to be grabbed. Upon grabbing all tokens in every stage, you get sent to this special final stage, and the game ends. This simplicity made for an enjoyable handful of minutes, and it killed time just as I wanted it to.
There are, of course, quite some problems. First of all, sometimes you only need to grab tokens in, say, two more stages, but the random stage selector takes a long time to finally send you to the stages you need, leading to a bit of annoyance. Also, I wonder why you bothered making the shooting cause recoil, if this was supposed to be retro, and retro games are not known for having recoil in their weapons. The recoil caught me off guard more often than not, making me fall off platforms when I had just firmly found a comfortable position on them.
