It’s brilliant, I could play it for hours! You took the sliding and merging of 2048 and made a really fun roguelike. The game loop is great. I liked discovering what two tiles merge into. The game feels balanced, not too easy but not too hard.
It would be nice to have a way to see merges discovered and achievements obtained.
It has a lot of potential, with more classes, items and monsters. Great submission, good job!
