This is a good moment to discuss some of the things we left off the feature list and other plans for the game and how we approached things.
Mouse sensitivity is a fair comment. Adding controls for that was discussed. But it's a game jam not a AAA game. We had higher priorities. It will be in the DX version we planned for after this.
My mouse is set to 2850 dpi and I also found it a bit high the first time on that level. It was double what it's set to now. I'm guessing you also have a high dpi mouse, mine goes up to 8000 and that was certainly not playable.
We also discussed adding some disappearing panels inside the vent that would make it easier. Again that was left off for time in favour of more important features.
I do think that the difficulty scaling could do with tweaking. Level 1 would benefit from some more time to learn the mechanics and get comfortable before adding a hard jump.
That said I think most of our team are dark souls fans and are of the view that as the industry trends towards easier games we have lost something of value that makes games so enjoyable and memorable.
A note to future players. The game has controller support and the control stick settings are much more forgiving.
Your comments have been shared withh our team, thank you for taking the time to play. I do hope you consider trying with controller.
