I really like this. I am sucker for a rather stylish-game using minimal graphics effectively, by combining it with great effects! It hits a great spot of being clear, but without feeling stiff. The button animations, the lights, the pulsating radioactive core and the really awesome table-flip transition. Have always felt that the power is in the details, and your game is spot-on!

For a jam-game, this is a great production, with only a few smaller issues I found. That said, if you look beyond that there is some space for improvements/development. As Vanne already mentioned, the little switches where a bit difficult to handle compared to the rest. It also broke the input pattern, forcing me to "hold-and-drag" rather then just clicking, something I would not see as much of a issue if the game was longer with even more control types, but with only 3 button-types the input difference stands-out and makes it less elegant. You also had controls for turning/zooming, something that I feel is completely unnecessary in this version of the game. That said, if you continue developing it, I would love to see more complex boards where turning the camera or even zooming becomes a necessity.

When it comes to level design, you also did the right choice. Have a level to introduce the new button type, followed by a more complex level using that type, and later finish the game with a "extra-hard" level with a more demanding radiation-level. I feel you hit a good sweet-spot on the amount of time it takes to clear a level and the total time it takes to clear it for a jam-game. It never overstayed its welcome.

I think you already have a decent grip what could be added, but if there is one thing that I would love to see explored is the use of the board itself. For example: being able to rotate the entire board and have buttons in odd locations. I'm thinking of the game "Keep talking and nobody explodes" as a great example of this.

Love the game! A very strong jam-game. Hope to see more.
