Thank you for trying the game and for your comments. The only real negative comments about it have been regarding the difficulty, so I will be making some adjustments to that. Lots of exciting improvements on the way.
Logins already work, as well as leaderboards. Friend groups, collectibles and powerups are all on the way. If I can get a satisfactory control method for mobile that will be coming soon. So, if you enjoyed it like this, then you'll love what I've got planned!!
