After 7 hours I managed to win the game on hard :') AWESOME work you did there and it has some huge potential. a game doesnt need to be highly graphical to be intense! Just look at all the shitty games that rely on their graphics and bore us after 20 mins. I hope you find the motivation to expand the game as I would really cheer for it.
5* from me
