That's great to hear, thanks for playing! :)
Do you refer to the pop-up windows above buildings? The one with upgrades and stuff? Yeah I noticed that during playtesting myself and I'll definitely change it. The primary reason is that the game checks if the player hovers on either the modal or the building sprite and most of the buildings are quite narrow compared to the modals so it's very easy to hover off of them when trying to hover over the modal. It's annoying - I'll definitely change that.
