Finished the demo with all 10 health upgrades. This might seem like an odd question, but are you good at platformers? The player feels very overpowered most of the time.
I like how the armor makes you immune to weaker enemies/projectiles over time.
Using the mouse to place platforms when you move with the arrow keys and jump with "x" either requires three hands or two people. In general, this ability could be very overpowered.
Hyperdash works well, as in
FLaiL.
Having to shoot a block in midair then jump to avoid hitting a near insta-kill spike is fairly cruel to ask of the player just to save after the first boss fight.
Loading should probably be a menu item, not an in-world object.
Bosses have enough hits that you should probably show a health bar.
I didn't see any pattern for the block destruction after each hit in the third boss. Sometimes the blocks spawn over the player unpredictably. One block blocked the entrance and it wasn't intuitive that you could make a block jump by shooting it at an angle.
in no particular order:
Boss 3: There isn't a true pattern for block destruction during boss 3. every time he get's hit, each block has a 1 in 3 chance of being destroyed. I also programmed it so they all get destroyed when the boss dies. I guess that's not in the newest release, however.
Yeah, You're right, a boss health bar would be a good idea.
I actually didn't like armor being so powerful. I got rid of two of the 3 that were added so far.
Not being able to easily use the mouse platform is actually part of the balancing.
As for the difficulty, it's actually something I'm trying to work out. The next version has a lot more enemies in area one, and a couple new enemy types.
I'll probably release a new version after creating boss 4 and a few new rooms.
