Glad I gave this one a chance! I found it pretty hard to progress past the boss as death is quite punishing. Having to do a full reset is pretty standard in games like this, but that's usually because there's enough randomness to where the start of a 'run' feels different enough each time to keep things interesting. That aside, I feel like all the mechanics played really well together, and made for a quite responsive action game! I never felt like dying 'wasn't my fault,' etc.
Really fantastic game! With some more polish this could be a really solid long-term project.
