Great wave based game with nice visuals and a promising prototype! I had fun playing this for a few rounds :)
Some points that might be improved:
- adding some music and other effects for the planes, when waves start/end, for the fire/interactions (otherwise the audio is nice!)
- adding more feedback when a fire is ignited
- some sort of "currency" to spend to update and repair the ship between the waves (waves starting very fast right now)
- adding more and different enemytypes and weapontypes
- update the background to make the aircraft move through clouds or something like that
Nice and fun game!
