Thank you for trying out the game!
There is certainly a difficulty to the game. We had people on the team that thought it was too hard, and we had people who thought that its just the right difficulty or still don't have enough mechanics. We aimed for a difficulty where it can be done without death once people figure out the mechancis which are not numerous.
The dash is actually overpowered a bit but was a necessity to add for fun and to be able to make the fights a bit mroe dynamic. Movement will be altered post-jam to accomodate players who don't like the dash.
We were not aware of the audio bug because it doesnt appear for us in operaGX or edge. What browser and OS did you try it on?
