Couldnt place magnet when I unlocked it and had 0/2 module slots (i had 100 shard). the two upgrades near the start "spawn rate" and "spawn frequency" both mean speed of spawn, but one of them increases the quantity/amount of spawns.

Thank you for the feedback! The modules can only be placed on the highlighted areas near the edges, so it may have been a clarity issue. That said, I will check if there are any bugs involved with this mechanic.
Also, the two spawn upgrades are definitely confusing as well, so I will look into renaming and improving them.
