Played it to the end, got to max everything, visit every single place. Well:

- Needs music, badly. It would improve gameplay a lot.

- Upgrades are nice add-on, still, i dont see much improvement when u max them, in fact, i see maybe a bit. Enemies still need 2 hits.

- Not exactly random-generated enough, i would say. Needs more variety of rooms/levels.

- Medals would be nice. Like, when u get all items in game, max all stats, pass the game, finish without restarts.

- Optional: Boss. I was expecting one at the end of level 14, maybe halfway. Still, with other stuff mentioned, even without boss, would be great.

So, overall 3/5 from me.
