This platformer has a fun feel to it and is very reminiscent to some of the games from the Sega Genesis era.
The character, level design, and music reminds me a lot Ristar, which was on the Genesis console.
I do however, wish the appearance of the characters blended more with the backgrounds in a more seamless fashion.
Also, when Radar gets hit or dies, there's not much going on in the audio / fx department to emphasize his demise.
Other than that, this is a fairly solid play.
Keep up the good work!
