Hey, thanks for the review! I knew not adding a collision effect for the enemies was a flaw on the design, but I couldn't come up with a solution that was visible enough with the time I had (the money collission effect was created and added in the last hour before I submited the game).
I thought about the idea of making the character inmortal during the special attack, too, but also the time left i had to change it was limited, so I simply added more money to he cash register.
I'm glad you enjoyed the game ^^
