Glad to hear you enjoyed how the game feels to play. 22,550 is already higher than my first run😄!
The shop is there to let players trade relics, so they can build stronger setups as they progress through runs. In the next version, we’re planning to add a tutorial that will also explain how the shop works. A fullscreen option is on the list too!
Thanks again for playing and sharing your thoughts. Please stay tuned!
