I actually quite like how the shrink ray reflect mechanic plays, aligning your attacks is pretty engaging!
problem is, there's not much point to fighting enemies when you can just walk past them (*and* still get points for it!), at least as far as i got...
also to be honest i think the connection between the gameplay and the theme is a bit weak. you have a shrink ray, but it only works on projectiles, and the shrunken shots still hurt you, but it lets you reflect them? it's a little odd
