it is frustrating, if you are knowing, what to do, but it didn't work. So the frist 30 times I didn't get to the first switch by jumping, and suddenly I got it. But I didn't do anything in a nother way. after don't getting how the 4 switches work or not work to get the spring working, it was enought for me. Also some animation parts a not working very well, like the rock which kills you suddenly without warning after the helicopters. I think there is potential, but maybe you make your game less frustrating. You can design hard levels when the game mechanics and physics are work well and not when the player don't understand if it is a hard decision from you or is it a bug.

I didn't thought the game was that fustrating. I know the four switches in the first level are hard but a puzzle game was the condition for the challenge I did this game for. (To help you with the four switches: they have to be activated in a specific order. I think the order was 2, 4, 1, 3.) But I don't get why it took you about half an hour to get to the first switch. I think that part was pretty easy. The rocks are a bit tricky but the enemys aren't that dangerouse so the only difficulty are these rocks or lava. Therefore I didn't use animations for them. Thanks for all this advices. I'll try to change the levels so that they aren't that fustrating anymore. But I think I'll have to work on another game for the current challenge first so that may take about two weaks.

can't activate the spring with the three switches. The DoctorProfessor is out!
