Construct PRO

Construct PRO is a sandbox-designer, where you can assemble any structure using metal parts, bolts, and nuts and test its physical behavior.
Currently the game has the following features:
•    assembly of a model using 29 parts•    saving the model in a simple text file and further uploading the model from there
•    enabling the gravity to check physical behavior of the assembled structure
•    changing the bolt properties (whether they are screwed on tightly or not) both in assembly of the model and with enabled gravity
•    removal of bolts/parts both at assembly of the model and with enabled gravity
•    application of a special Boltogun, capable to destroy any model
•    use of electric motor for rotating the part attached to it
•    test prototype with possibility to complete the game with it: you should assemble a model capable to overcome all obstacles and reach the finish line
•    bugs (well, after all, it's an early access stage)
