I like the idea but I think it's a bit too hard, I died in 30 seconds, however I think you could improve it by adding more items and reducing their price to 40 coins, and making the ice cream have health then again, IDK if you want it to be hard. :D
Yes, it was intentionally designed to be a little bit more on the difficult side with 1 life :) but I agree, the balancing could definitely use some work! More items would be fun, too.
A quick little tip for the first level: Try moving things around :D
