Wow, thanks a lot for the review, I feel really flattered :D And thanks for the feedback - the mouse sensitivity didn't seem an issue on my PC, but I admit I mostly tested with a gamepad, so you may be on to something! The time didn't allow for the implementation of a settings screen, so that is something I might actually add when the rating phase is over.
The enemies are also something that could be improved with more time, absolutely, as is the punishment for dying. I'm glad it didn't frustrate you too much - adding chackpoints might be a great solution that I could add along with the settings. Thanks again!
