It's nice to see such positive feedback.
Also, to answer a few questions:
How long have I been making this?
Clip Single Player: Since last August, so almost a year.
Clip Online: Since December, so about 6 or so months.
Why is there no background?
I'm still deciding if I will include detailed backgrounds, because Clip Online used to look a lot more complicated than it does now, I have slimmed it down to make it a more simple and enjoyable experience.
(Example: Unlimited ammo, simple reloads, faster movement speed, cursors)
Intricate backgrounds are still in question.
There are achievements?
Yes, so far, for the Online mode, the achievements unlock EXP rewards and occasional bonuses.
There are 30 so far.
If I can, I may include the medal system from Newgrounds as well.
When's an open beta coming out?
Not until most of the glitches and problems are fixed.
Also, not until I am happy with all the features included.
Open beta will be released when all noticeable bugs are fixed.
