I played it through to the end and I liked it a lot!
Some thoughts:
- I'm not sure if abilities should change shortcuts mid play, even if you plan on there being more than 10 it might be easier to go beyond numerals, but keep the shortcuts static
- I played quite actively but I'm not sure if there is anything preventing a purely passive play (it might take a few more runs to get the abilities, but eventually every enemy gets auto-deleted)
- There could be a hint in the menu if there is anything purchasable in the skill tree, so I don't need to go in if there isn't
- The skill tree is hard to navigate and hard to read
- I not sure if randomness is good here or not, on one hand it rewards attentive play, on another it somehow breaks the mantric repetition, idk
Good stuff! I would like to see more of it in the future.
