I mean, technically it's not a puzzle. It's just a simple inline-4 oriented upwards. But that's the only category I think anything like this will probably fit.
Awesome Mechanism !! A very cool idea! The piston system is well thought out and very stable! This is great. Well done! But the gameplay is very simple, for this 4.
I do not know if I should rate this level because the truth is that it does not have much playability... but was fun to see
@Denis Nazin If you noticed I have multiple rotators driving the entire mechanism because sometimes it will seize up (despite not actually seizing up) and the torque of one motor is not enough. So I used two, and for safety measures I added two more. It is able to run for more than 30 minutes (without jamming up), which is quite a good record for me. It's really really old. It's about 4 years until I decide to publish it. Playability, well, because I don't know what to do. I mean, obviously the map isn't big enough for the bot to crawl around the crankshaft, so ... But to get the bot to move from one piston to another isn't a total walk in the park, either. Lastly. I like the fact that people are actually enjoying it.
