Fun take on theme.  I think the game needs a little better balancing but I got what you were going for. Good job.

Nice game concept, it was fun spawning the aliens! That astronaut is certainly a tough one, swinging the sword and other weapons! I liked art and animation very much. Good job! :D 

good game, i couldn't damage the player but it was nice

I really enjoyed this game! It's better than Vampire Survivors.

Good game, but very hard. The astronaut leveled up to fast for me (though that's likely my fault) and I wasn't really sure whether the expensive unit was worth it. The amount of resources needed to level them up first made me avoid using it.

Great work, I found it a bit difficult to understand the point of the really expensive unit.

Interesting concept, and one I've been thinking of prototyping for years myself! Glad you've done it so I don't have to...

Well presented, love all the details like the animated menus etc. It's not super clear what's happening and what you can do. Needs a couple of hints to onboard you a little better. I only figured out I could spawn new units by clicking in the edge after I'd already lost twice!

I'd have also appreciated indicators showing what the different units did, how much HP they each had, how upgraded the each were etc. Likewise with the single hero - how much health does he have? How much damage does he do? Explaning these things to the player in a clear and concise way would go a huge way to making your game feel better.

As it was, I played about 5 times, and in the end could hold the hero off indefinitely. I never new if it was possible to defeat him though. I could see my "money" clicking up at a decent rate, and spawned in a few of the red guys. They died quickly just like the cannon fodder yellow guys. I had expected them to behave differently, like maybe have a longer ranged attack or something.

Still, well done for getting a totally working game done in 48 hours. Not an easy feat at all!
