Warpspeed 2 (bullet hell in 3D and on acid) Universal App, 3 levels for free

This looks cool, I'll give it a go! Lovely dot tunnels in the video.

Couple of suggestions:

1. Don't call it 'bullet hell'. Bullet hell is where lots of enemies are shooting at you and the whole screen is full of bullets, and you must find a safe path through. Think "final boss in a shoot-em-up". Not really what your game is about judging by the video!

2. Can the HUD be turned off? Not the actual control parts, but the big grid across the screen - unless it's got some purpose it's getting in the way of the sexy graphics you've got

Ok, just had a very quick run through. It seems good! Very smooth and fast, lovely graphics and sound, the controls feel great, and this kind of game is always fun to play. I reckon you'll do very well with this

Some more suggestions:

Add more free levels. I'd say 1 or 2 more, and definitely a tunnel level with obstacles. The free version is a bit too short - not quite enough to really get into the game. You need it long enough to get into the game, not so long that people don't need to buy the full version.

Rework those HUD graphics. You don't most of the in-game overlays, and they're in the way of the game. If you get rid of the metal bars and move the speed/damage up to the top (and make them thin so they don't block the view much) it would be perfect.

Last thing: improve the end of the level. Either make a special 'end of level' area to replace the black part, or just make the tunnel a little longer and fade to white if you want a quick fix
