The game is really fun at the start but you hit infinite power pretty quickly after a couple of regen upgrades and then you can spam all of the other upgrades until enemies die on spawn. I like the concept of health = attack speed = currency, but it makes hoarding the resource a really broken strategy because of how much damage it gives you.

Our idea was to have a single resource that could give the idea of "investing on yourself", of course the game still needs to be balanced a lot, sadly we didn't make it in time before the deadline. We will definitely add some missing details and work better on some aspects of the game that need to be fixed! We really appreciate the help for improvement and we want to thank you for trying our game!
