Thanks a lot for your feedback! I really appreciate it and i'm glad you enjoyed the game
Yeah many asked for SoundFX to give some more weight/impact to the actions in-game, with the next update that will also have an outdoor zone, NPC with dialogue boxes, A LOT bigger dungeon, a real Boss and other things, it will also have all the proper impact and other sounds (and probably a new background music), just need to do the finishing touches (and find some free time from work lol) and i will upload the updated builds.
If you find the game hard i suggest to try blocking and attack enemies during their cooldown, you will have a nice opening there! Or the best and the fastest way is to hit a parry and go for the combo (Light Attack then Charged Attack)
