Ooops I got a crash at the end !
I love how you managed to build tension with the energy management and the relentlessness of the enemy, it always felt like I was always on the edge, fighting for every second I could get.
It got even more scary once I noticed that it could destroy the terrain walls too, it's a very nice touch.
The art style is really cool, the gameplay work perfectly, that's a very solid game overall, well done !
