I recently reviewed Gravity Lab! On Slimgamer, and I was taken back by how well developed the game was. In a similar fashion to Cut the Rope, players must collect stars in Gravity Lab! to unlock more levels. Collecting all three stars on a level unlocks additional bonuses and gives players extra currency, which can be spent on cosmetic items.
The concept for Gravity Lab! is pretty cool too – players can rebound the protagonist against different objects within the level in the hopes to knock the four different block types into the three stars. Each block has it’s own gravitational pull towards an individual direction.
