Thanks for playing our game and for the detailed feedback!
- we have lot's to do to balance the difficulty, one thing could be less enemies in early rooms
- rewards for killed enemies is a great idea, didn't think about that yet!
- the hit box currently depends a lot from where you stand as it's bound to the player skeleton, we intend to complete rework this to make it more flexible hitting above and below you.
- Yes, upgrade costs are too high for the current state of the game. We'd love to fix it but have to wait for the upload block to be lifted.
- Dash direction and indicator is something we still need to work on. We'll definitely test if its better to dash in the WASD direction instead of mouse. Thanks for bringing that up!
- The dash and the run speed are something that could be tweaked, both as a starting value and as potential upgrades.
You're feedback is immensely helpful, thank you again for taking the time!
