I finished all levels and tutorial by 100% and didn't get a single achievement. (Achievements in other steam games work fine). Is there any fix or can someone help me to solve that issue?

Lens position is slightly changed after last update so you can't beat it. So I had to download old version. 1. steam://nav/console 2. download_depot 504400 504401 142533863162835804 3. Profit?!

if i buy Optika i will get 3 or 4 free trading card drops or nah? i wanna get the background it looks cool

I'm having issues completing Level 6 on "Let There Be Light". I can't actually get the speed required to trigger the level complete, as it seems that after a certain point, the lights will start passing completely through the mirrors.

Come on devs, it's not that hard.
