Nice little game. Easy to win, but took me a couple of games to max out my score. By some abusing (selling most of the turrets at the end) I've reached the score of 1350. Different damage to hp and shields was a bit confusing, because it was written just as "health" and "shield". Good overal, nice turret models, nice base, nice gameplay. And some familiar spaceship models on top of the map :D
Would like if the camera movement speed was higher, it's not very important in the game but somewhat irritating. Survival mode and visual difference when upgrading turrets would also be cool, but I understand it's a jam game with limited time. Keep up the good work!
