I have major ideas for this game.i would think these ideas would be awesome in it:
Classes. a selection of classes without having to spend points earned in rounds. i have a few class ideas along side upgrades (which cost points).
Knight. the knight comes equipped with a sword and a shield that blocks swords in a bigger radius. you can upgrade the shield to be bigger and get a spin attack upgrade to your sword.
Ninja. the ninja gets a bigger sword (2 pixels to be exact) and can throw tiny shurikens that are faster than arrows (but cost half an energy bar). the shurikens can be upgraded to be 100% bigger than normally and can get a ninja slice that makes you instantly go the distance that ten robots side by side make, slice anything in half in the line you went. the ninja is faster on foot (25% to be exact) but doesn't block very well at all.
there is a major bug i found that has gotten me killed a lot. the sword doesn't register sometimes and arrows don't register much sometimes either. i also find archers sometimes invincible to swords and bows, wasting time and effort.
my final idea is giving players 1 more point for every boss killed. it would make it possible to add classes in and add more upgrades this way.
