This game is quite enjoyable. The asset remind me of those Atari-era game, so it has some stylish point despite being simple. The game itself is easy to understand and work quite well. There are few points I think could be improved:
- Faster fixing tower time: Since it's not like we are defending the tower or anything, I don't see the point for a long fixing time
- Make the scanner work better for close range: I'm not sure if this one intentional or not, but the scanner has trouble detect mines at close range (behind the first "wave").
Other than that, great game you made there.
