Great game! It feels a lot like an arcade game; I played a bunch of times and I got a highscore of 107! Very well polished! Could easily be an addictive mobile game.
Pros
-Cool intro screen, a bit low res tho
-Loved the aesthetics and music!
-I liked that there was a tutorial, but I didn't really help (Though I learned I could get gems with my pickaxe from it). I had to play the game a couple times to learn how to play.
-The forced rail movements added a lot of difficulty to the game
-I liked the darkness effect (maybe added in some bloom through post-processing to make the gems look really shiny :D)
-I liked the pickaxe movement. WSAD/arrowkeys lane movements wouldve been a lot easier, but this adds a lot of complexity to the game. I think it would have been cool to make the pickaxe range unlimited and let the pickaxe movement go concurrently with the auto-lane switch rails. So you could buffer lane transitions to make multi-lane transitions.
Cons
-I wished the mine hook would move a bit faster given some of the situations I was put in lol
-I encountered some situations where i was surrounded by enemies(two rocks, 1 bat) and I couldn't dodge no matter what lane I was in. I realized later that the bats could be killed with the mining hook.
-Would be nice to have a sound volume slider
-Not sure what was at the end of the timer since I never made it, but I felt a bit rushed by it.
Awesome game, great job everyone!
