@blackksirius it really isn't that hard; i missed a couple jumps here and there and still would get like 10 secs under. its all about movement optimization and taking what short cuts you can
+ this if after the boss, you upgraded the hell out of your ship to fill it completely with all level 5s just to re-fight the boss! I know i did and I owned! :)
I agree with ayoth. You should explain you can only click green blocks and have somewhere other then the description that your destination is the white blocks cause we all know a lot of gamers are too lazy to read instructions. Add a tutorial level or two and maybe in later levels, add red blocks or something that if your guy touches them, he dies; that way it will add a little more challenge to it. All in all, I see this game having a lot of potential to be a very challenging, but fun, puzzle game. message me when it is done and i will beta it if you want or just tell me when you publish the full game and ill play it then. Good luck! :D
