Thanks for playing:)
For the manual & automatic controls, I planned a system where the player has to attach some of the automatic controls in some levels, raising the difficulty in a way. I think the balancing is definitely going to be an issue, but I will see if I get to round 2... Thank you for the compliments, I'm glad that my simple testing ground would work:) With more time, I think all I would do is to make all the equipments first, then worry about the game itself(so the project wouldn't be that much better even if i had a while).
Thank you so much for the detailed suggestions! The battery recharge idea was really creative: I think I would implement the recharging on surface. For auto-rotation and opacity, I would definitely try to make this idea in game, as well. Current rotation system was definitely not perfectly implemented and was confusing for some players.
Thank you again for such a detailed review!
