Yeah, it works now and the .dll is in the folder, I do not know what I did wrong before!
It is a cool concept!
The level editor works really well, really like that you have different themes that you can choose from, made a few small levels, was really fun!
I think the jumping of the character feels a bit floaty, would've been better I think to increase the gravity and possibly not have the charatcer jump as high, but that is a personal preference.
Overall great job!
