The game felt great to play, but the balance was quite bad. You earn way to little money, for quite weak upgrades that you don't even need to win. I bought ONE sword and a couple of character upgrades and beat all of the bosses. This might be because the anti-boss potion was is OP.
The loader upgrades are way to weak and expensive. This problem becomes more and more apparent until the other upgrades literally don't do anything, and the loader upgrades are to expensive to buy.
The game requires stupid amounts of memory, so please add some options that remove animations, or something along those lines, so it's actually possible to have it running in the background, without eating 2 gigs of ram.
We'll be adding more options to the settings screen. Also, we'll be inspecting memory consumption and improve the performance.
