Thanks Jordi, cool that you like it. Since the demo update from two days ago, the respawn has a short animation and time of 2 seconds (until then it was instant restart - if you like watch an older video on YouTube) because of the feedback from people with epilepsy and other conditions with sensitivity to light because this would a breaker.
But you know what, it's a development process and I'm not finally sure about a (let's name it) "speedrun" mode without lives but with a counter of "deads" and a timer from 0 to >.
Really appreciate your feedback and download. :-)
