I did end up playing this game, though my computer gave me like 3 warnings. I think it's because it's an installer rather than a zip file. Like, that's what viruses and keyloggers and such do. Every time I went back to the first screen, I got a pop-up telling me to log in and that made me a little suspicious, even so.

I actually kinda like the jump mechanics. It looked like you drift up until you hit a ceiling and then drift back down. It reminds me of that game VVVVV where you navigate by flipping gravity. You could make some cool platforming challenges with that, maybe make it so you have to bonk your head on specific things to keep from flying off the map or into spikes. It's kinda underutilized, though, with the levels being so small and simple. 

I only got 3 of the endings, loop, pit, and alien. I bet the 4th ending has something to do with the little white object on the 3rd screen but I couldn't figure out what to do with it. Pit and alien felt more like deaths than endings, but they were both out of he way so they weren't really level hazards or anything. The art style was pretty alright; I think it was the best thing about the game. I'd say the level design needs the most improvement since there wasn't really anything to it, no challenge or misdirection or anything. Some music and sound effects would be a nice touch as well.

Altogether, it's alright as a start, just needs a little more. And maybe look into a different way to pack it so it doesn't send up red flags.

Um... why is your download page quarantined? How'd that happen, what did you do?

I'll check back later to see if it's fixed, try your game then.
