Really unique and well-polished gameplay, I really enjoyed it, especially once I found out that if I don't charge the sonar, it will still travel the distance, only at a narrower angle. It feels really rewarding to shoot one of those thing at the last minute.
Some improvement ideas:
- There should be a way to turn off or tone down the screen effect, it was really hurting my eyes after a while.
- It would be probably friendlier to reset the player to the beginning of the same level instead of level 1, or maybe give three attempts before the final reset, it feels bad to lose all progress.
- Some kind of a narrative, even an intro and some small snippets before each level would really add to the feel, while I was roaming those halls and looking for these weird monstrosities, I felt like I want to know where I am, what they are and where they came from.
Overall, nice work with the smooth gameplay and the sounds effects.
