Manolober, a better alternative to "infinite lives" pokes could be, to release a v1.1 of your game (alot of people, who publish a game here, later make updated versions of it) and in this v1.1 you then could wipe out some of the weaknesses from v1.0, like for example the big speed-increase that happens from level-2 to level-3 and so on. The game is already good, but it's normal, that in a v1.0, often not everything is absolutely perfect. Using "infinite lives" pokes is no longer a playing-challenge for the users then, because they can go on forever and play as bad as they want with this, but an improved v1.1 could be a great idea. Maybe you also have own ideas, what else could be improved, then also this could be realized in a v1.1 ("giving points" (depending on the used time) and a "highscore-saver to disk" would be nice, for example). Some people here release five or more updated versions of their game in the time after, so this would not be a problem. Maybe you can do it by your own, or you find someone, that could help you (on CSDB maybe, we already wrote about it). That would be great.
Thank you so much for writing to me: I agree on all the topics you've touched on.
I entered the infinite lives to give the player the opportunity to see all the levels and also the ending. It's not a great move but someone on csdb cracked my game and this crack isn't even that good.
The best thing was to immediately solve the third level problem: something I've done only in the last few days (if you're interested, I'll send you the poke).
The idea of inserting points based on time or numerous precious objects is very nice: I will try to insert it.
At the moment I'm in contact with a group called Hokuto Force who intend to put me in their group and launch a better crack made by them. But I don't know when they will.
Maybe on Itchio I will publish the development page with version 1.1, as you say too, where the speed of the third level will be adjusted. Thank you very much. Until we meet again.
