I enjoyed my time with Hekko. Which was about 52 seconds, as I beat it the first time I played it. Then, I enjoyed exploring the environment and trying to leap out onto the ground to see if there was anything up there. The radar system, once you figure out how it works, is very effective, but perhaps isn't congruent with what people are used to wrt radar systems.
Its a nice little package and an enjoyable diversion, it has the sixty seconds in as a time limit - it could be more themey, I guess, given the single level doesn't really hammer it home. I get the impression you had an objective/plan and stuck to it though, due to the early submission. You did a good job picking out the art pack and building on what was there, and I think you wrote a sufficiently compelling story to tie it all together.
Just judging it as it is, I think this is a neat submission, but one that fails to leave a big impression, either negative or positive. However, that's usually the sign of a great foundation - this game could go places, and you did a good job of assembling the pieces that are there into a complete package, so, well done!
