While the game has some fun mechanics, I second what was being said about "no goal", although you do mention, that it's just a "proof of concept".
- Good thing you've made the temperature meter freeze, because the Fahrenheits don't tell me much xd However, the meter still doesn't reset if I freeze, so I have to re-run the game to play again.
- Combat is kinda difficult, because of how fast and small the projectiles are, but this is more of a statement than criticism.
- When the enemies chase me around the building, the front walls cover them.
- No sound!
