I watched the game on Retromation and it looks very promising.
Here are my tips to fix the current issues:
- add countdown timer to the next wave
- this will promote to finish the wave as soon as possible instead of stalling
- if you finish soon you can spend the next turns healing, shielding or stacking energy before next wave
- add different scanners
- scanner for 1 energy to reveal a few random unrevealed tiles
- 7x7 scanner to reveal 9 tiles (corners + middles)
- 10x10 scanner to reveal 16 tiles (corners + 2 middles)
- other shape scanners (line scanner, circle scanner)
- some would reveal predictable symmetric patterns other random ones and it would be up to the player to mix them properly for maximum effect
- add cooldowns to some weapons/abilities to make them more precious and also to encourage having mutliples of the same type
