The heartbreaking moment when you really appreciate the game although it's really challenging and really want to prove to yourself that you can do it if you try your best and you spend way too much time on it because you keep making mistakes but you are so determined and then you finish level 16 and the badge somehow doesn't award. :^)
How to get the first badge - Run around in circles til the max number of ninjas spawn. They will be running towards you so seeing as you run in circles they will be constantly changing direction and therefore will remain roughly in the middle. When you have five or more in a little cluster, go for it. Flashing weapons mean they're about to charge so make sure you don't attempt to kill them as their weapons are flashing. I got a 6x combo easily with this. OH, IMPORTANTLY, the badge only triggers after you die.
Just figure out the path beforehand and keep the combo going and you'll have 50k points easily. I got up to 52k having not even completed level 40. Good luck :)
How to get the badge: Play Dead On Time twice, after that you should have enough money saved up for a gun. Buy the gun. Start a third run of Dead On Time, when you see a zombie in front of you SLOW DOWN or even stop completely so that it gets on your windshield but doesn't die. Once you've got a moving zombie on your car, you press F a few times. Done.
Right, I've finished all the levels twice now because the game claims I have 33/34 rubies when I've picked them all up. Anyone else having the same issue? Wish it would at least show me the level where the last ruby is apparently. Dear Mrjinx, any ideas? :/
Weapon upgrades are useless til late game. I found upgrading the pet first to work just fine. I'm currently on a laptop with no mouse so I wanted to be lazy and not have to shoot at anything til Im in space. Got both achievements within 20 minutes.
Brilliant game, here's a handful of tips on flying enemies: have a staff and work towards the best one, have lots of health, keep running from them and never run alongside them as damage multiplies quickly, wait for them to come down and fly on your eye level, then quickly turn around and shoot at them. If you've not killed them and they're too close to you, run through them, wait for them to come back chasing after you, rinse and repeat.
For those asking how to do the daily badge - talk to orphan at first town, talk to penguin family at second town (you reach 2nd town after defeating the first boss), you talk to orphan again, you talk to penguins again (this time the orphan is with them), you get the badge. The longest and most complicated bit about it is the fact you need to beat 6 levels in order to unlock the second town. It's pretty nice and easy.

Right! Ok. Just over a year to reply here, but maybe you're missing the training level gem?
