Thanks a lot for the feedback!
Controls in general need a some rework I agree. Web gl doesn't help but I think in general there is improvement to be made. For the wheel bot I think the approach I tried was wrong. It work but doesn't feels satisfying to control it. For the rail bot I think it's mostly fine tuning it would need and making a special control for the last level. Instead it should place the light where your mouse is and not the bot.
Great ideas and suggestions!
