This was pretty fun! and then when I got to last stage i got so irritated, My strategy whether intended to be or not was to manipulate the bottom two plugs as a stair case where, where the 3rd one remained plugged to unseal that long bar above the poison pool; every time I would retract the one beneath me to jump on top of the one that came to me until eventually was able to reach that ledge and got up there but, then my vision screen space couldn't not see the left bottom of the level cause I was too far to the top right. I was trying so many things.
Something that was really confusing was telling which plug I would be in control of. It felt like the one that I was manipulating would switch to the plug that was connected to the socket when that was not the one I wanted to retract. It's either obvious and I missed it, intuitive, or at random? I could not tell. It left like it was randomly choosing a plug, though I could tell a likely plug interaction would happen because it had the radius which I assumed meant more likely to interact with another appropriate object within the radius. This was clever. I think you should consider a more obvious way to tell which plug you were going to be affecting if you click on it, causing whichever one to retract. This was my only major confusion on that last puzzle with the 3 plugs. But this is likely my skill issues XD It was hard to tell which Plug was gonna retreat back to where it started when I felt sure I was trying manipulate a different one.
I like riding on the plugs, I died in a lot of surprising ways, which was hilarious. I was so determined :P
I liked the color scheme. Simple and seemed well executed. The readability is great, nice saturated and unsaturated values, nice contrast. I love red and blue together, makes my brain fuzzy. The gameboy-esque music was nice.
This would be a fun project to see develop and to watch where it goes. Also to learn more about the character and if there is a story behind that character and within the game itself.
