This game is amazingly fun! It blows me away that you guys made this in only 48 hours. With some minor improvements this game could ship as a product I would say (based on just having played it for at least half an hour without tiring of it). Kicking ships and rocks together, and shooting a ship into unending orbit is a lot of fun.
I think it might be a little fairer if the bigger ship maybe would not do as much damage, but that could be part of the charm. Definitely make armour stackable. That would encourage more danger-seeking gameplay, and make the pickups more interesting when you already have some. The engineplay worked incredibly well, most of the time. The times when it doesn't, it gets frustrating. It was not always clear why I couldn't blow my engine while butt-facing a ship.
I would love to see this game fleshed out further, it's a blast!
Pun intended.
I was discussing the game with one of my teammates yesterday evening, and we came to the conclusion that a co-op mode would make a really awesome addition. Although it would be a lot of work to implement, due to the small amount of buttons required, a one-keyboard approach with either split-screen or a single stretching screen could work, no online stuff required.
Co-op would allow for a bit of teamwork, bouncing ships and especially rocks around. Also, it would make it more managable when the RNG spawning system screws you over by spawning multiple huge (!!!) ships on opposite sides :p
Have you guys made any games before this? You seem like you knew what you were doing.
