Thanks a lot for your feedback! Nice thing you pointed out there, the souls were added at the end, I didn't notice they heal too much until now. Indeed double fire rate zone and simple enemy AI made the game too easy and repetitive. To improve this, I'm planning to do one or more of these:
- Add more enemies with more complex AI
- Add more zones which will make progressing easier and possible (some are heavily needed)
- Implement some sort of move to not die mechanic (not moving deals damage)
- Time limited prizes for exploration and movement (Some sort of damage bonus, speed bonus, temp prize crates)
- Your idea modified, Each situation or enemy needs a specific power-up, so you need to move
Thanks again for playing the game and giving feedback! Things will improve in a post-jam version.
