great start to a game---has a lot of potential, add a crap load of special features and units and all the convenient tweaks and you got yourself a nice strategic tower defense----the idea of upgrading not only the towers themselves but also the castle is very good....good work for now but you have a lot to do
nice game broski, i really enjoyed playing it! Maybe now you can add even MORE UNITS and MORE MAPS, and I'll be sure to come and play.....nice work 5/5
Also, for ahcievements, you could have beat so and so level in X amount of rounds on at least Y difficulty. That would add an extra flair of replayability.
things to add:
1) Able to switxh direction easily
2) smoother action
3) more combos and
4) need the space bar to also pause the game
5) allow for powerups and or different weopens
