I didn't think this game would get badges until the dev made it save game progress. Leave/reset the browser and you have to start from level 1. Aside from that, a neat little game, but way too short. 3/5
I don't know if it's just bad luck on my part, but I've yet to get any health packs in survival mode, which pretty much makes the hard badge and impossible one. Though even with health packs, surviving four boss tanks plus turrets surrounding the place still seems impossible. Also, I got 99% kills and got a silver star. Seriously? That's just ridiculous. 2/5
I hit "main menu" by accident when I was on lvl 8 and now I'd have to go thru it all just to get to that point? That's poor design right there. Saving progress will be necessary if you ever hope for badges.
Salty Squid, after you fall down in that center area on 5-5, wait until that middle log stops spinning or at least slows down...it should eventually tilt just enough where you can jump on it and have enough angle to quickly jump again before it throws you off.
For those claiming they have 25 lives left and aren't getting the badge, you have to beat the final stage and have 25 lives after that (which for me meant not dying). The only levels I lost 1 life on were 1-3, 1-4, 2-2, 3-3 & 5-2. Every other level I beat without dying.
