First thing you do: go to gacha and use your two free pulls. The advanced will likely give you a 5th character - your team can have 5.
Then, regularly between the stages go to raiders and click the levelup button. You need to do this actively and it will make things a lot easier.
I finally got the badge. How? Dunno, just staying out of sight of the contested point and shooting the walls at random angles. I wish the game gave you a clue which team you're on, because the teams are orange and blue and your own tank is green and everyone is shooting everyone anyway.
For the pet badge: don't try to get the owl to level 10, get a combination of 10 levels across all your pets, that means keep farming the low dungeon and boss for pet cards, so you can switch between owl, unicorn and fox.
Level 14. Place towers on mana. Place 4 red/green towers around each bend as kill zone. Only dump xp into kill towers.
Before ninja mobs, place one green at each entrance to mark. Don't upgrade. Never dump all mana, keep some for nuking, you'll need it.
Around level 35 place 4 crypt on elevated ground, slowly upgrade them to fear crypts.
Level 44 start saving mana.
Level 49 sell marking towers to make sure fear crypt hits boss.
Cross fingers, fear or freeze him and you can beat him before he reaches the gems.
I don't think the game design is bad. It's an enjoyable and original game with a simple ruleset, something that's pretty hard to do, as many of these ideas are already taken. A lot of the negative criticism I read is caused by the game mechanics not exactly accomodating a player motivated to grab the badges. The badge requirements are choices made by someone else than the game designer and the original game was not designed around enabling badge hunting.
To get the medium badge: Claim your diamonds a couple of time (so you have around 10k and can afford the 2.5 Sx knowledge upgrade). After you purchase the 2.5 Sx knowledge upgrade, make sure your champion is set to Audrey and combo 1+4 with added 2 as soon as available for knowledge points. Grab the hourglass as your first 10k research. Don't klick the stone to not break your idle bonus while doing this. Good luck!
Issue #1: The hover box obstructs the most important information on the deck upgrade buttons, which lands you on
Issue #2: Even though the left button is still grow-animated, moving the cursor to the very right edge will unintentionally upgrade the button on the right side "slow but strong" instead, which results in
Issue #3: Slow but Strong is an outright downgrade that will ruin your savegame without a chance of undoing
I love the game mechanics and it's well made and stable. I'm not very excited about the graphics, because I find the optics rather dissatisfying, even though I like minimalism. I find the music and the sound effects horrible.
Hi! I'm an old lady and I just earned the badge. It's less skill and more persistance and practice that got me it and I'd like to share some general tips: You don't have to beat the dev score on every level. More than a thousand people got the badge but less than fifty ever beat the dev score on L4 for example. Don't beat the dev score, beat your own highscore. In the levels with the standard beamball rules (like fading lines, chromatic swap etc.) your orientation is way more important than your location. The only levels with standard rules in which you have to move around a lot are D3 and D14.

To be fair, I had a hand in deciding what the badges should be. I think the design of the badges are aligned with my design of the game.
