One of my faves so far, really cool twist on a classic genre, well designed and looks good! Great job :D Small improvements suggestions:
- hide the mouse cursor while playing
- Feedback when ship gets hit

nice little game, kinda wish I could be not a scaling up/down ship but an alien with an ability to grow/shrink. overall, very neatly done<3

Good idea to have the certain level of fire power and shields depend on how small or big you want your ship to scale, I would prefer if you had your health back up to full after you kill all enemies on screen and picked an upgrade. Other than that, good work!

Lovely artwork on the background of this game. But the font and its form meshing with the background is causing me little bit of an issue to read. But the overall gameplay is quite enjoyable. The scaling is very specific on number and makes a good mechanic. Good job for this game! :)

very fun game! i wish i was able to scale up and down faster but overall good game!

A good bit of fun. Stats between phases was enjoyable.

Very interesting take on the theme! I really enjoyed the aesthetics of the game.

such a unique style, loveee the background work!

Cool take on the theme! The art looked nice, and the game was very enjoyable! Congratulation on making this!

Loved the retro vibe, great work!

Its a fun game with great art. I think that the pickups drop a little to fast and the enemies feel like they have a lot of health. but overall a great game with the scale mechanic nicely incorporated.
