The game has a lot of potential! Its very fun to try and compensate the stats to try and optimize your run and take shortcuts! 

One thing I'd say is frustrating is the lack of "Menu" button in game, since if the cards you pick make a level unfinishable, its annoying to have to quit the game and re-launch it all over again. It would also be cool to have in the "Deck" menu a more detailed explanation of what each effect might represent in game, so it doesn't rely totally on trial and error!

I can see this game potentially having very complex levels, and piling up all those cards makes each run unique and interesting to try and navigate the levels in a new way, well done on this game!
