If I had enough time I would have implemented more pieces and more mechanics to make puzzles more challeging, and I plan to keep working on it to reach this goal.
Thanks for the feedback!
Very nice game, I like playing it, discovering the power-ups and dodging enemies bullets, an idea would be defining keymaps for each power-up so you can easily build combos, unfortunately the game crashed after some time playing, and I personally didn't found the color scheme very appealing, but the overall experience was very enjoyable. Nice work!
I am sorry for that, I should have write more instructions in the game page.
Basically you start in build mode where you can move the islands to build the puzzle, by pressing space, you enter solving mode, then you can move the pieces to capture each other until one piece remains.
Thanks for playing (or at least trying).
Releasing the mouse when it's out the window seems fine, but the code I wrote says that you can only initiate the impulse when the box is colliding with the world (not best design), that could explain why the clicks doesn't work sometimes, I'll look further into this to make the game better, thank you!
