All of this is said in the game but just in case.... arrow keys moves you. Space Fires. I for items shop. U for upgrade shop. 1 for grenade. 2 for spike.
Comment any ideas for any new upgrades or items, I'm going to try to keep making this game better and better. Slap the love it button if you had a good time! P.S. It pauses when you are in a shop so dont worry. :D P.P.S. This was a school project (can you believe it?) so keep the comments clean please.
