Depends on the level, some levels have farther between the checkpoints (they are invisible). When you play on serious, you have no extra lives from the start, that means that when you die you get game over and will have to restart the level.
Play on normal for a more normal experience.

I want a serious experience though ;)

The save system sucks - the game saves at checkpoint; you can't do so manually
Problem is you're not sure what to expect as a checkpoint; there's no notice 'Checkpoint Reached' or 'Saving Game' message

I've wasted thirty minutes of playing time thinking that if I dropped out where I did it should auto save

This is a game to avoid if you have a backlog; far too time needy

Actually, there is a "saved" message everytime the game saves. It appears on the top of the screen when you reach a checkpoint.

For me the save system is also weird. I was now in the (I think) last level and I died near the end of the level due to a countdown timer. Then a message appeared that I would eventually need more time and resarted without any other choice the level. That sucks.

In general there are these checkpoints, but on a Game Over you are asked anyway to restart the level or go to the main menu. I was always going to the main menu and loaded the checkpoint save. Don't know if this is intended.

I think I will let some time go by before I replay the level again. And if I loose again at the countdown, I will use ALT+F4, its so strange.

sounds like an older method of save system was added in
checkpoints, and then last checkpoint is saved then overwritten once you start the level again, or a new save point comes when you have restarted.

i would hope and think they left the last save option in there to help players
but one never knows, been so many save systems over the years.
and long ago we had passwords, before that nothing x.x the darker days ive heard of
were you either finish in one go, leave the system on, or other means lol
