In the mobile (more recent version) the scrolling stops you at the start and end of the level - it doesnt loop like the jam version...
Updated itch version so you should get an email from them about the update 
Finally got a chance to try the update. The player controls much better now. The scrolling no longer stops when moving. It's actually pretty fun. Quite challenging too. I find it is best to actually play while watching the radar instead of the playfield.
Do you think this might be a good game to try get some interest out on Steam for a more extensive version?
I think if you added a good amount to it and also made it a little easier it may find an audience on Steam. Steam gets a good number of people who like retro style games. For example, if you look at the games in
my Steam library you find a strong preference of retro style games. You'll also see that I recently purchase AGK2 and have been spending most of my time playing around with it. lol
For Steam I'd want more of an experience. The presentation in your game is excellent. The graphics and sounds are very nice. I mean it doesn't need to be some epic experience like
Environmental Station Alpha (32,000+ sales on Steam) or
ORCS (6,000+ sales on Steam).
For example
Bit Blaster XL (120,000+ sales on Steam) is a very nice game. It is very simplistic but very well done. I think the main thing is to provide a good entertaining experience. Make the game easier in general. Start out with a simple level so the player can get the hang of it and that feeling of victory from completing the first level or two. Then throw something different at them. Etc. Maybe give them one other thing to do like collect X things along the way.
Games like ESA, ORCS and BBXL are very much like the kind of games I have an interest in making.
I have these two games on GameJolt (both can be played in web browser or download for Windows):
Atlantic Crisis and
Treasures of Ali-Gar. They are fine for free web games but if I was putting them on Steam I'd definitely add more to them. Atlantic Crisis would likely be turned into an adventure of sorts with scrolling screens and just a little more to do in general. Treasures of Ali-Gar I'd probably add some RPG elements to it such as different spells, mana generation and so forth.
Just my opinion. I kind of rambled on there a bit. Sorry about that.
