Connection to the theme: 5/5. I guess those were simpler times?
Enjoyment: 2/5. It gets pretty boring after wave 9 or so.
Presentation: 2/5. Can't say much about it, it's pretty plain and the lack of any music is really a shame, but it's not completely raw either.
Gameplay: 2/5. The gameplay loop comes down to running in circles around the planes spamming LMB, occasionally changing the routine to pick something up and to shoot.
Creativity: 3/5. The whole setting, the paper planes as enemies and a cardboard tube as a weapon are pretty unique I guess, but overall it's close to the general template of such games.
