Reached the end and smashed the orb!
There were only couple of bugs I encountered - after ice cave next portal led to room with 4 pillars and they were missing textures when I approached from the side; second note about inventory was not readable, unless I would turn to the side and mouseover it then. Idk why exactly that note - others seem to be fine, except notes on the floor - I couldn't read them fully, since text would be cut at the window border. Oh and there was sound in the library after I beat that fire guy... that was looping right around him, but I couldn't quite understand if it was bug or something I missed!
Other than that I would also love more snappy movement, but it was all right to be fair - game wasn't too long to make it an actual issue. I was kiting everything, since mobs were reacting too slow for that movement anyway!
Really cool that there were several weapons with their unique style. I loved machine gun ice everyone after i got it... though it didn't last too long :D
