Good level, but you can win easily by using the free draggables. I like the design of this level, and i believe you can do even better when you do more levels.
It's a good design. The red brick is all a bit ugly, but then it's in keeping with the 'evil' in the title, so that's ok. I played it as intended and it's a good game, but many will just pull one of the free draggables onto the win block. (They are missing the fun if they do!) If you fix the draggables onto sliders, or maybe secure them between sections of wall then it stops people cheating.
I'd recommend that you stay away from Free Draggables as I won your level in 9 seconds without moving B. See video Spoiler: Video I'll now attempt to complete your level as intended.
@LPaGGG - with a slider. See card. The 1st draggable isn't anchored or set and can win but the 2nd draggable can not win. Spoiler: Card
@LPaGGG Here's a link to a redesign I did of a level that had free draggables using anchored sliders instead. You might find it helpful ... https://mekoramaforum.com/threads/free-draggable-design-alternatives.516/
