it looks good, try to have set time limit to play in the specific era until the game will advance to next era or"Evolve"

I realy enjoyed it!

gamemaster3, jamezogamer101: Thanks!

I have added the second part now. The only thing I might still add is sound effects. Apart from that, it's finished. Have fun!

Sound effects have been added as well. I consider this finished now.

Liked it, but the way the bullets behave is really frustrating (The collision is a bit off)

Charming MSPaint graphics :). The enemy variety also makes a nice balance. I have to gripe about the collision though. So many times I thought I would be able to fit through a gap, but I would collide with what appeared to be nothing and die. When you do stuff like this, you should make the collision boxes only the size of the visual enemy, not the size of the entire enemy image - or at the very least, crop the graphics more closely to get rid of empty space in them.

Nice, but realy hard because of big collision boxes.

In this simple game we can observe the hard life of a fish xD

What I like most is the game's size that is so small :)

LOOOL I love the graphics rated humor 5 it maked me laugh nice retro style game. Reminds me for one of my first games I made

The only problem are collisions boxes, but it's a big problem. ;)

Like others are saying, the biggest issue is the collision boxes. I really liked the gameplay - it was balanced and pretty fun. I played for a while without dying, but couldn't make it to the dinosaur stage. Oh well. I had fun!

I like it despite the collision boxes, and nice graphic style

It's really hard because there is no life points and the collision boxes are kind of weird. But I like the idea anyway. :)

The hit boxes are way off and I got frustrated very quickly. Good job though for a 48h game :)

Charming! I couldn't get past the fish though...

I feel like the player has not enough influence on whether he gets hit or not - this probably has to do with too big collision boxes, as the others already said. Couldn't make it to the dinosaur stage unfortunately and I muted my pc, because the sound effects were getting a bit annoying.
I love the mspaint-like graphics and the idea of having two game modes.
