Thanks so much for playing! Yeah since it was our first jam we wanted to focus on making a good short experience to help avoid overscoping, but if we were to build it out into a full game this would be more like an arcade mode type of thing where everything auto-scales and you just try to last as long as you can, and the other game mode would allow you to choose upgrades after each level or something like that.
Played & rated your game as well! Was fun seeing a totally different 'arcade' type game.
