Combinatorix

why am i watching the widget of windows ? XD

The idea is good and the puzzles are well done ! The tools and UI are intuitive.
I think you should consider to add a Menu and/or Title.
In my opinion, the timer is not necessary.
I find the backgrounds cool !
Well done, all the best !

nice. but use a different background. You can try with wood or a table. The space is not good for this game...
