Your game is quite fun! It was hard to pull myself away from it in an attempt to succeed, though I do have some feedback.
Particularly, there's a pretty good chance you get soft locked for the pipe minigame- The electricity moves too fast in comparison to the incompatible pieces you (can) get, but it certainly has potential! I think simply having made them rotatable would've made it better.
As for the tetris minigame, really enjoyed that! It's a unique spin on tetris I personally prefer more (Not much of a tetris player to be fair!)
Overall, very lovely game! You guys did a good job for what I assume by the game page is your first project (In godot at least)
