Thanks for the feedback! I recommend that most players end at the end of dungeon 2. We have tested all the way through twice and have found no game breaking bugs, that being said Dungeon 3 is much more challenging and i would not recommend it if you had a hard time with levels 1&2. For anyone who does finish it though qutos to you. Just a few tips for anyone who wants to finish the game all the way through.
Blue particles means you are near an invisible enemy use the candle to see them. They are one taps even with the axe.
Sneaking let's you pass most enemies
Look for traps on the floor it only takes one to kill you. You can disarm them with your axe or by shooting them
The boss room in level 3 is unlocked by unlocking 3 consecutive doors. After getting each key unlock one of the doors this will save your progress.
