It's not necessary to test on multiple device (but if you have time it's a bonus for me :) ).
I'm really waiting for your feedback, Thanks a lot :)
I'm currently testing it out as we speak and I'm currently typing out all feedback (so far) in a Word document which I'll then copy and paste over when I'm done.
EDIT: Testing on both a smartphone and a tablet.
I've tested the game on two devices and have added feedback to the post. I tested it on a high-range device and mid-range device however if you want me to see how it runs on a low-range device (dual-core CPU) let me know and I'll bring that out as well.
