-Doesn't seem to be any kind of failsafe preventing you from spawning your construct halfway into the ground, as long as the core is not in it
-Or launching your contraption without a core altogether
-Building a swastika desintegrates the entire construct in a matter of seconds (probably for the best)
-The physics in general is vehemently against any kind of non-wheeled design
-Pistons (the normal kind) are not able to push anything attached to them
-Hinges don't seem to be functional, since attaching anything to one resulted in the corresponding item disappearing
-It's the same kind of fun you'd have in a game like Besieged, but extremely simplified and hardly functional at the moment
-The visuals are rough, but I didn't really expect much from a prototype. Servicable for proof of concept
-Cute robot core
-Weird coloring choices when making incorrect decision in part placement (sometimes you go green, purple, orange or red). I know that some of them mean that you've attached the part in the wrong way, but the others are just bizzare. Explaining them (in-game) wouldn't hurt
-No way to simply copy previous part you've used/keep using the same one you've chosen until you run out of parts
-No "clear" button, every single part has to be un-attached and dragged towards "delete"
-No way to reassign hotkeys or change the properties of certain parts (like making certain wheels have reversed controls)
-No other settings aside from barebone ones
-Having basic controls in-game (even if written somewhere in the background) instead of itch page would be great
It's like Besieged but made by the devs who only heard about it from a guy who really liked Elastomania
Also here's a bit more structured review, with some extra bugs and even a link to video illustrating some of them
