Cool and interesting mechanic. I'd introduce new frequencies later in the game and not all at once. Separate buttons for each frequency instead of switching them would be better I think. Maybe the echolocation circles should be a bit brighter and the points shouldn't disappear when swiching frequency but stay there and slowly fade away like normal. Overall good game that can be improved and expanded if you want ;)

This game has a cool concept and a creative idea! I really like the usage of three different waves for different objectives. However, I think the implementation of that mechanic was a little lackluster. I really wanted to have fun with it but it didn't quite click for me. Perhaps the mechanics were introduced too quickly, or maybe the silhouettes should have stayed on screen longer to give players more time to read. Something felt missing in the core gameplay loop that prevented it from reaching its potential. The creative concept itself is very compelling and shows a lot of promise. Overall, this is an interesting entry with a solid foundation that would benefit from polish. Would love to see this idea expanded upon!

I like the ambiance, though found I kept wanting to press each number key to do each sound wave. overall, it was fun but very challenging

I think I have nothing  to say that wasn't said in previous comments, but cool mechanic! (I would suggest tu just hit a different button for every frequency rather than "choose the frequency button" and then pressing "sound button", but it's just personal preference about gameplay style :)).

Creative take on the theme. Well done. I think the number keys to choose frequency would be great. I often press 1/2/3 instead of shift lol. I won the game after getting that box thing.

Unique idea, wish there was more in the way of gameplay though (stopped playing at the combination lock). I think the controls could also be better, pressing x takes occupies one of the fingers usually on WASD.

I was freaked out by the ambience. Haunting game. Even more scary since I couldn't figure out the order for the numbers :(
Good job!

Rly like the idea ;) Challenging as well!

the mechanic Idea is very unique! tho at first it's unintuitive where to go

Coll Idea, but I was also stuck in the first level, maybe it needs a clearer description on how can you interact with the level

Quite interesting premise! I got stuck on the first level. I wouldn't blame the game for this, since it is quite late here, and my brain is not braining.
