Been quite a while since I last played a space invaders-ish type of game. I like this one, the skeletons were very well drawn but I wish they were more animated. The level up bonuses were a bit unbalanced, I think multishot and rapid shot were by far the strongest, and the explosions hitting you was a surprise I was not expecting. The game is also not technically 1-bit because the health bar became grey once you emptied it out, and the particle effects were also fading, but overall I think this is a very pleasant addition to the game jam. Good job!
