Hey there. This would be a good game for those who are in relationship and test whether their synergy is truly sweet and go well together.
The game's concept is simple. There is a man and there is a woman, and we simply need to have both meet each other. The premise is simple. Under that, the game proceeds as puzzle levels where both the man and the woman must cooperate. It is a must to have 2 players to play this game for the game to shine brighter than the sun.
However, I believe this is an alpha stage of the game. All the concepts and what not are in. What are left is to polish and ensure that the game experience flows well to the audience.
For example, when the man and the woman meet, we could show both the man and the woman slowly french kissing each other (and add a sound effect for this). This will give the players (or lovers) the gratification of accomplishment together.
Another instance is when one of the lovers hit the laser (?), the stage simply restarts. To ensure the game flows well, there should be a sound indicating one of the players is hit by a laser as well as disabling the movement for that player. After that, the game could splash an image showing an "ouch" image to the lovers, then restart. This will allow the game to flow better, rather than simply restarting. Yet, I do understand that this is your first game, but this game shows that you are now ready to proceed further in crafting richer experience. :)
The puzzle itself is intuitive and you always know what you should do. Nevertheless, a tiny mistake could punish the lovers to repeat the stage over, doing all the things they have done in the past minutes. This disrupts the flow of the game and could irritate the lovers, yet it could be easily fixed with a quick auto-save and allow the lovers to reload to rewind and fix their mistake. Does Unity have such feature?
Other than that, great job. Keep up the good work.
