Thank you! Ideally we'd like the make it so that most of the game you are being chased by the light, but for that first level we wanted to let the player understand they need to avoid the light without putting too much pressure on them.
I think the levels could definitely do with some further fine tuning, I'm aware that you can get past the light at some points that mean you basically can rush through the level. I'm half-tempted to make sure this can't happen so the player needs to be mindful of the timing, but at the same time if you're fast enough maybe you should be rewarded by being able to rush through (but is that fun though?). Something to think about, so thanks for raising it.
The lives system is a recurrent criticism and we agree, we will do away with it in a future update. We may count the number of level retries (so the player can try to best it), but if we're aiming for the same sort of difficulty I think we should not punish players to much by having them restart the whole lot.
Thanks for playing and for your feedback!
