I wish I would've had more blind playtesting to catch the shop issue, I heard the comment a couple times... It kinda makes me sad that some people could've played and totally missed that feature altogether.
The tank kind of threw off the economy balancing - it was an addition the morning of the submission LOL. It's probably better for the game jam because it allows people to play with all the perks/skins, but I definitely would look over that in future revisions.
Thank you for playing and the great feedback!
