First of all, I'm really glad that this game exists, and I hope that one day it will feature cross-platform play between Oculus Rift, HTC Vive and PSVR, just like Star Trek: Bridge Crew, because this is one of those little things that made the game quite popular and let us enjoy VR a little more.
Now, about Echo Arena:
- I couldn't help but hit some objects in my room, even though I feel like I have enough space for the game (2 x 1.5 m / 6.6 x 4.9 ft.) This reminded me of Rec Room, where I bumped into my environment, but there's a nice feature that helps you prevent it by showing the center and the direction of your play area. I think it would be a good idea to show this under a player, and maybe even above them.
- The frame frequency overall was quite good, but sometimes it was lower than usual, especially in the main lobby, when you look at the center of it. I'm not completely sure if that's just my personal problem, but from that perspective I'd say that certain elements might need a better optimization.
- It would be nice to let the players turn left and right with both sticks. And, in case if you're going to release Echo Arena for HTC Vive as well, I suggest an optional feature to turn around by double-tapping the touchpad, because I often found myself turning around when I didn't want to.
- And just a tiny little suggestion that I want to tell most other VR game developers: give us an ability to make an "OK" sign by making a circle with a finger and a thumb.
That's pretty much all that really caught my attention.
I love your game, and I hope to see it grow in the future.
