Thank you for checking the game out and for the detailed feedback :D
Would definitely keep this in mind as I try to improve upon the game.
Also I think the 3 two-tier items not combining was an oversight on my part,
item combination only happen once every spin, therefore if a 3 one-tier items have combined,
the 3 two-tier items will not combine until after the next spin end.
(I plan to change this to make the combination effect more rewarding)
Thank you again for playing and kind words !
