Interesting idea, but I found the level with the pit and the three upside down spikes to be too difficult. I would prefer being able to select a floppy with 1,2,3,4 and then place with the LMB. Also, removing with RMB would be useful, so that you don't have to reset everything if you mess up. Allowing for starting with Space or Enter, and reseting with the R key would be nice as well.

Yea its missing some of the quality of life stuff that might have been good to have.
Also it likely wasnt you, because level 9 & 10 are impossible in this build, due to differences in the engine and build mode (idk why that happened).
I uploaded a fixed version as a comment under the normal game page, in wich all levels should be playable.
