Dude, this is a very good project (especially considering it was made for a jam). I really enjoyed playing it! The visuals are minimalist but they look so cool!
If you make the gameplay more fluid and faster (I’m not sure if you kept it as it is intentionally or because of the limitation of constantly instantiating objects, but if that’s the case, maybe it would be interesting to use object pooling?). That way, the experience could feel smoother and more dynamic (just to justify, this is only my opinion, not me laying down rules).
(Additional rating points for the Oppenheimer reference haha)
