It's fun :D, maybe a little bit buggy (coins not counting, despite being rendered after being attacked, able to get "infinite" coins by attacking a goblin during it's death animation, in some cases very low amount of chest spawning in unreachable areas (pockets at the very top or at the very bottom and instantly covered in lava. Goblins seem to miss one or two sprites and turn invisible in combat at times. It is possible to "fall out of the map" at the sides, delivering the coins is finicky, would probably be a bit easier, if the time machine would attract the coins on short range.)
Still pretty nice :D
