Thank you very much! Yeah, there is actually no checkpoint system, we didn't get the time to do it. Now that you mention it, maybe using a floppy disk for other thing was confusing, thank you for that feedback. The floppy disks at the begining are for decoration proposes, althought in the second level when you access the 2D level its a platform you can use (because it gets on reach changing the perspective)
Regarding the big jump, if you are refering to the one in the end of the 3D level, there is a ventilator after you jump the last ram :)
Thanks for the feedback! We will be playing your game in the following days!
