Good music,simple visuals.But very bad controls.I manage to get 141 score by few tries but it feels to much random.As i can understand robot trying ro move sway from enemies,but it also doing some random moving too(?) .Because of this you have only few seconds to survive,cos robot definitely will run into lava.I think game ramps up too fast,needs more slow introduction to stimulate player try more next time.Overall not bad,but i cant play it after few minutes of constant lava deaths :D
Also cool idea will be to add upgrade system to improve ai behaviour over time,something like in my game.And another one is add separate button to be able blast cubey in other direction(like big shot for example) on right mouse button.This will make game more simple to control and can be helpful to shot strong enemies
