A very cool game that will make you think how am I going to pass through this level. The concept of leaving something behind to guide you to the exit is really clever. However, the jump once is so weird for a jump. Releasing a jump based on the current concept of the game is weird but yeah maybe that is the way it is designed. Would also be cool if the robots have their own super unique abilities and are limited to make it even more challenging.
Overall, great job and this game is so nice to play. :D
