Heeey! It's not your fault, the game infos are not 100% clear yet and this circuit it's not the easiest for begginers, one of my bigests concerns is the lack of tutorial and how it affects the gameplay. Idk if you realized the Diagram Guide in the ingame menu, maybe this menu its not visible to you, depend on your monitor resolution and aspect ratio (i had a hard time trying to do a responsive game, and i've failed xDD). Well, i'll post the Diagram image here, in case of you want to try again, but no obligations, and if the diagram dindt help you that much, i've created a resource that helped me to properly configure the game to upload here... you can press backquotes and then a little console screen will surge, you can type and enter the code "fillboard" (whitout the quotes) and then select the values of the components, and complete the circuit in a easy way (this may bug the game because, initialy, i've created it just for me)
Thanks a lot for your comment, it is realy important to me, because I want to develop this game to be a educational game, im glad that you like the graphics and had a funny time trying to solve the circuit. If you try again, with the diagram or with the fillboard command, let me know! Sorry for the long text with grammatical problems :x
