Thank you for your responsiveness, one door opens well, but the bottom one does not open completely, even by jumping it is not possible to pass through the door (see image)
Thanks for the hotfix3, it's strange that the game starts directly on an unknown level, lives are infinite and shooting the button doesn't open any doors
This is the level I just worked on (level 17) should not be playable yet. I have uploaded a different version. Thanks for the tip . Forgot to change it in the code ;) Now everything should work again. (new version is online)
ok, the door opens, but I must have made a mistake, one door remains closed (see image) and it is very difficult, if not impossible, to back out with the spikes going up and down.
