Thanks for this absolute unit piece of feedback! I greatly appreciate it! <3
I am planning to implement all feedback after the jam's rating period is over. I will try to figure out a way to better telegraph the movement penalty and make it feel more polished.
The idea of adding a reflect or spikes mechanic sounds like it could be great fun. Could make for a new "battering ram" strategy.
Also appreciate the reported bugs, the pausing one is one that was not known of beforehand. The second bug with the tab switching I have not been able to reproduce yet, if you can supply me a video via Discord I'll be happy to look into fixing that one.
I am already working on adding more flesh to the background and environment, that so far has been one of the most requested improvements. Same with true bosses and different drop types.
I'm really happy you had a great time playing my first jam game! And thanks a lot for the huge amount of feedback. <3 :D
