oh and the skool can be really hard when you're trying to achieve high combos. Maybe add an upgradable combo presever which saves your combo if you run out of time but only for limited uses (1000$ 1st shield, 2000$ 2nd shield, 3000$ 3rd shield). you shouldn't add too many shields cause that would ruin the challenge maybe limit to 3?

Personally i would like some upgrade some upgrade in the bank. Maybe make a interest percent upgrade but it should be expensive. A interest bar speed up upgrade would be also nice.

Freedom it's called a genre of lenght games with the goal of reaching distances in a somehow original way i don't see ppl rating down like Cursed treasure don't touch my gems down because it's like a million of other games but has the original good touch to it and it's a very addicting tower defence game!!!!
maybe you should make an inventory of like 10 spaces and the game automatically collects items until it's full
you could then sell the items for their prize.
