ok
this demo is fun ,has enough content for it's length ,the upgrading method is new and enemies are well designed specially the boss
problems :
the map doesn't show the door location which is annoying when two rooms are next to each other without a door
their is no way of knowing if my equipped weapon if weaker or stronger than the weapon in the shop (coloring the numbers or putting an arrow next to them will solve the problem)
if the melee weapon in the upgrade menu is on the left ,why is it's crystal displayed on the right (same with ranged weapons)
the game needs music (even a simple 8-bit them will work)
why do i lose my crystal charge on switch
and side problem : the quit button on the game over menu doesn't work
