Small thing but took me quite a long time to find the "cook me that gif" button on a desktop. Would have expected the Add Images, Edit and Preview and Share Gif status items to all be clickable or look less like buttons.
Thanks for pointing that out! The cook button should be pretty loud, so I'll look into how I can make sure it's not missed.
I agree with sleepychu. The interface was largely intuitive and laid out. The text at the top looks like a tab based interface and I too tried to click to go back to the edit step. Even having definitely seen the "cook" button (hot pink! yay!). Personally I'd buttonize (!) those texts top-center and add "cook" before share. You should probably consider changing it from "cook" to something more obvious - make, finish?
When I look right and left I see other elements of the interface off-screen, but again clicking here does nothing; seems like these should be active areas that move to the relevant "tabs".
It looks like you're probably going to add user accounts as a premium option? Seems like a possible monetisation. There's a company that turn gifs in to hologram gifts I think, might be a good tie-in, or they might license your editor.
When reddit get hold of this your server is going to explode with memes. I'd take a cue out of imgurs book and roll with that - add a top listing, hot now, etc. in form of thumbnails; consider allowing comments.
Lastly, I assumed that the giflr link would both share my gif and give a prominent remix option, but it didn't seem to do the later, I could clearly just start a new gif and insert the old one but that seems a bit clunky.
