FOX n FORESTS is a game with a few really great things going for it - including its charming story and mostly clever level design that puts its clever season-changing mechanic to good use. Unfortunately, a few aggressive flaws quickly sap the fun out of the entire experience, including forced backtracking; annoying one-hit-kill autoscrollers out of nowhere; and its overall short playtime. It's difficult to recommend the game overall, but it might be worth it for hardcore retro platformer fans.
With a bit more polish, Copy Kitty would stand the test of time like the games it sets out to emulate. But despite its flaws, it's a strong title that uses its desire to emulate overall better experiences to create something unique, interesting, and most of all, enjoyable. If you're willing to overlook its flaws, Copy Kitty is well worth a look.
