Engine Keeper - Ludum Dare 46 The Jam [upd1]

We have made a small game for Ludum Dare 46. The theme is Keep it alive. In our game, you have to manage the engine room of the spaceship so it KEEPS FLYING. Items in the room are not obvious because we haven’t been able to finish that part. On the wall, there is a line with 3 rockets. Its the space race your ship takes part. Your ship is green! Every time you pump energy into the engine, green ship advances. The guide on how to finish the game is in this video. build2
