Nice puzzle game! Liked the mechanic of rotating and analyzing the shape until we'd find the one fitted, especially with the timer making us more attentive. Although, I gotta say that there could've been a better way to rotate the pieces, I feel I should be able to rotation in the azumith axis to align it better. Other than that, well done!
And it's interesting how both of our games work with unlocking doors!! So, if you want, you can play ours and rate it as well :)
