Lol! Thanks for playing. Yeah even I, the programmer, would forget such a simple mechanic during play testing. Lol. Perhaps we need a better way to remind the player of the mechanics available to them. Thank you for your comment :)
I wouldn't say the player needs a reminder, I think I'm just too tired to pick up on it when staring at the screen.
In puzzle games I always tend to go for the most complex possible solution only to find it was something more simple.
lol. I hear ya :)
