The changing mechanic is interesting, but a lot of these effects are too op. See if you can balance it up a little. And feel proud of yourself. it's a pretty legit first topic. ;)

Most of the people who play this game are terrorists. I am. You are. Spaghetti mom is. Get over it.

Shields are pretty expensive, so adding buffs would make them much more worthwhile to buy. Your shield buffs are a little op currently, but it's a pretty good idea. Keep in mind that the game works better when simpler. Don't overcomplicate.

Mostly they're just for fun and variety when playing. There would be rewards if the game mode is winnable, but if players are just fighting in a different map, then you'll get the same rewards as you would in the normal ruins. So yeah, it's basically just cycling modes.

Guys, please don't post ideas for maps in the comments. just make your own post.

Wow those sprites are good. This is a great map idea. The only way I could think to improve it is if you added some places where items spawn.

There could just be piles of rocks lying around, and when you hit them, the throwing rock items will pop out. With every rock that is taken, the pile would get smaller. Kind of like trees, but rocks instead of stamina/health orbs.
