This is an incredibly impressive and fun game! Your interpretation of the theme and special object is quite creative, and you executed it well here. The game itself was really fun: the VFX makes each hit and enemy destruction feel satisfying, the difficulty is well balanced yet still a bit difficult especially when trying to destroy enemies while managing RAM, and the upgrade system works quite well. I did feel bad though that the game ends quite early, but the base premise of this game I think can lead to a very interesting roguelike game concept.
Good job!
