So, I like the mood of this game but it needs a lot of polish.
-The music feels like two melodies competing with each other at times which becomes distracting.
-Tiles are tiny and a bit annoying to click, this repeats with the items in the shop. for the shop the clickable space should probably be the whole square where the item is. for the tiles I can imagine pressing space to raise the tiles to select them from a new horizontal bar that pops where your mouse is, or pressing num row numbres to pick letters.
- Let players learn the game at their own pace, pop up instructions when they choose to press on tabs in the shop. or maybe it's just my preference.
- A lof of things feel rigid, tweens can do wonders for making the game feel more interactive.
-discard tiles by throwing them somewhere, it would probably feel way better than pressing one by one
- use the mouse movement(velocity) to rotate the tiles as you drag them
-allow clicking a tile again before it stopped "select" tweening to revert the selection, players losing inputs feels bad
I got stunlocked due to the way I built my board after a few rounds and also the browser is less than ideal to play. but I generally like the game. good luck.
