Quite fun, could be a great game if you expanded the plot a bit.

Maybe if you made the sonar slower and longer, but you use it less, it might be easier to navigate.

(Maybe have an energy bar which drains if you sonar too much…)

Maybe you could include different types of 'sonar'

I.e A red sonar can stun nearby enemies for a few seconds, but it takes a huge hunk away from you energy bar.

And maybe make saves less frequent, but you can do various things at them, (maybe recharge energy bar, equip different sonars ect…)

I can this this being quite an excellent game if its expanded (maybe a few more enemy types couldn't hurt, but if you design the levels well enough, you could keep the game fresh for quite a while)

Good luck. Keep working on it. Its pretty awesome!

(although my comp. lags a little when I save, but thats no problem…)

Thanks for the feedback so far. Some really obvious things which I just didn't think of (pressing space all the time does get annoying, for example).

I think having different sonars would make it too complicated, and it's not very original imo.

Maybe I can make it so that you can turn on your sonar with Space, and also turn it off with Space. That way you can keep it on for a longer time. But: like someone suggested, when you use it a meter will go down.

What this game is is really just a very simple idea, made into one, story based game. Maybe I should indeed expand on the story, hmm. It could be an incentive, or reward for the player to keep going, if I presented a bit of new story every now and then (and make it compelling).

Hmm… I have to say, that is quite a good idea…

Well, first thing off, pressing spacebar to use sonar is more of an annoying and repetitive task than one that enhances the game.

I think sonar should be taken in a different way, more of a pulse that you send out. Think about the way a bat uses sonar. It'll send out sounds when they choose to, but it becomes like breathing to them, a habit… mashing spacebar doesn't seem like a habit to me, I'm not sure about others. :P

Spacebar could be a sort of concentration mode, where things become clearer to you; or adapting it to Retro's idea, it could be an attack.

Also, I think the sonar should show what is within reach of the actual sound, as opposed to showing what is within the screen. Possibly, "special blocks" could be put in, that you can hear through. Its purpose would be to show that there is an important item there, or something of the sort.

Also, a memory of sorts should be set into play, maybe one that you can level up, and where you can level up your ability to "see" using your hearing.

If I think of anything else, I'll post it… Like I said, great idea, just I would have done it differently.

I like how different objects have different sounds. However, I must say, it does become kind of become a pound the spacebar type thing.

I have to ask, where those just place holder graphics are were you shooting for the retro pixely look?
