I've just purchased the game. I just hope you won't drop the price too fast!
Anyway, it's a great game. Nice concept.
I also like the new planned features. They would make the game even better.
However, I'd like to suggest to along with "slide" an alternative method to move rows and columns: tap the goal slot.
Sometimes I can't slide properly and tap the slot would be a lot easier IMO. OK, maybe not a lot but it'd be very handy for sure.
In addition, a resume game is really necessary. Sometimes I can't finish a game and I've noticed that when I start Slide It again my started game is gone for good.
That's all for now!
