I really like the concept — it fits the theme of “everything has a cost” perfectly. Shooting coins and then having to collect them before they disappear is a clever mechanic, and linking your damage to the number of coins you have adds an interesting risk‑reward element.
Once I realized that the bats can’t pass through the coins, I figured the best strategy is to stay in one corner instead of moving around to dodge them. Using this approach, I managed a score of 177 on my second attempt, though I’m sure I could have done even better.
I think the gameplay could be even more engaging if there were rooms with a limited number of various enemies, similar to Smash TV on the Master System. But what you have made so far in the jam time is brilliant! I enjoyed playing, thank you for making this!
