It feels like Research scales very very poorly.

Easiest hard badge ever?

You can get hit and still get a "perfect" rating, you just can't lose a life. Once you have all 5 hearts your goal shouldn't be to never get hit, but to only get hit 4 times. You can plan your movement more effectively this way.

Soulbound/combination charge items need to have a very low, but non-zero, chance of dropping from non-bosses. This would allow players to have some power creep and lets them see real progress over time.

Don't save up for invincibility for the impossible badge. You get "F" ranks even with pacifist.

Don't use the cheat if you want the hard badge. Your score shows up as Cheater and you don't get the badge. Just wasted a ton of time this way, and there is absolutely no warning that you won't get credit. Absolutely absurd.

This seems like a great candidate for an impossible badge...

A tip for critical training: turn on the sound and close your eyes. The two different sounds can be much easier to react (or not react) to than the different images.

I've gotten a 223 block combo with little effort. 80 is easily doable with decent mouse sensitivity settings.

About time badges got removed from this game!

Somehow I lost all progress when I refreshed the page, despite having storage set to unlimited. Not cool.

Less than 10 infected for 10 days straight, running full campaigns on that state, with them barricaded in. What the hell.

I hate launch games, so I'm probably a bit biased, but this felt WAY too long for a badge of the day.

A combo of 74 did it for me...

...third try? Just make sure to stay on the right side of the screen.

I think the badge is currently given out for reaching level 4 (in the top left corner), not from completing stage 4.

"Wow, I'm going to get the hard badge without the medium badge"...then you get to the final boss.

When you need a cauldron, go to the outskirts house and place the pot on the stove.

The horse is the real hero of this story.

@will2345676, you got the first two badges in July of 2013. You didn't get the hard badge until June of 2014. If it took you 11 months to get to the point where you are getting 2k coins, coin acquisition is too slow.
