Ok, you should be able to play it now. I made a resizable window and placed the button on top of the title if it's still buggy.
Thanks for the update! Ok so i got to play the game and these are my thoughts: The game concept is very original because as far as i know there is not other game that has a mechanic similar to the ¨Hack¨ one. Also i liked the fact that there were some levels where you actually needed to use the power ups from hacking in order to progress during levels. However, i think the enemies dont represent a serious treat considering how easily you can avoid fighting them yet only killing the one with the upgrade you might need to obtain an specific power up the levels requires you to have. Also, there was a level in which you had to make a big jump with the purple upgrade and it was kind of hard to land because the white warp-point was too small and also the character has no shadow to indicate you where you will fall so you have to predict your landings. Finally, i think the boss was WAY too easy, even if it is the first boss you should make his projectiles faster and maybe spawn a Yellow enemy so you are forced to use that upgrade in order to defeat him. About the controls, i think they are ok but i didnt like the fact that the character auto-jumps when near a corpse from a defeated enemy. Overall, i think the game has a BIG potential that if you know how to take advantage of it it will become a masterpiece.
EDIT: just noticed there is actually a yellow enemy in the final stage so yeah you should make the boss´s bullets faster hahaha
