are u sure u did this on only 3 weeks? it has the feel of something done in 6 or more weeks, at least at the art and music level..im very impressed with this game, its entertaining and fun and looks good...5/5 stars :)
was fun :) only issues were selling and spells, selling is a little tedious and spells are hard to time right but other than that 2 thumbs up for managing to keep me here for over 3 1/2 hours trying to beat the game
....1 map does not a game make...point 2...the game is not fun..if it is not fun it is not a game. point 3 no music, point 4 no effects, point 5 terrible art, Point is this is not a game.
i would recommend some tweeking of the weapons and perhaps using per pixel collision detection instead of bounding boxes. I get the occasional shot passing through the edges of the aliens and also, if i hit a single enemy more often than not the entire cluster of bullets disappear also id prolly try some shots that spread out in a Y sorta thing maybe as a power-up. Other than that its not bad.. but it has more potential.
...major problem with moving and shooting...i recommend not having the ant aim in the direction u are trying to move in, have him aim wherever the mouse point is
