Hey this is really good! I found myself playing this more than most of the other games I've tested so far. It's simple, but I like the ability to upgrade and see how far I could get! It did feel like I should get to blow up a big boss at the end, so hopefully that makes it in at some point! Really well done. I think a variation of enemies, sounds, and artwork will help this go a long way!
Thanks for playing! And ya I had plans in the work for different enemies but didn't have the time to fully flesh it out but I'm glad you enjoyed it. I'm hoping to put in a little more work to add in those few missing elements and a big boss would really pull it all together, thanks for the advice!
