Edit: Jacob lowered the price from $4.99 to $1.99, so I'm giving the game 4/5 stars.
Excerpt from the full review:
The ruleset delivers on being simple and genre-neutral (geared towards slightly heroic antics). I love the open design: no classes, free-form skills, mix character roles. I like the task resolution and the combat system. Within its scope, it offers a lot of flexibility.
It pains me to say: I don't find the game worth the $5. Exodus System SRD has some neat ideas. With its lackluster presentation and the high amount of alternative (free) games, it still falls short.
I would have liked to see it as a Pay-What-You-Want product. Then add a "premium PDF". It could have a nicer style, some artwork, digital bookmarks and "exclusive content" (e.g., more roles).
This is a reading review, so take it with a grain of salt.
