An interesting, well-implemented game with competent writing and appropriate length. The story is of the pretty standard "precocious youth of the future" variety (cf. Lost in Space, Meet the Robinsons, Jimmy Neutron, although Grounded's youth seems to be older than his counterparts in these examples), with the first scene consisting of the protagonist getting in trouble with his parents, causing him to be sent out in a spaceship on his own. The primary puzzle (and the only puzzle that will provide more than a hiccup during a traversal) is interesting and fits well within the game's setting and plot, but going from realizing the solution to implementing it is somewhat tedious, with some interface battling and calculations required.
